FEATURES - OPERATION

OPERATING INSTRUCTIONS
1. Move the power knob to the HI (II) position. 2. Rotate the mist volume knob from the smallest to the largest graduation to regulate the mist output. We recommend the use of a hygrometer which reads the actual humidity level in your room. A humidity level below 20% can be unhealthy and uncomfortable. The recommended humidity level is between 40% and 50%. 3. Rotate the mist outlet to the desired mist direction. 4. When the humidifier runs out of water, the transducer will automatically shut off and the fan will keep running to dry any residual water out of the base. 5. Turn the Power Knob to the OFF (O) position and unplug. 6. Before refilling the tank, empty any residual water and follow Daily Maintenance instructions. 7. Refill the water tank with cool fresh tap water and replace onto base. DO NOT fill with warm water as this may cause leaking. 8. Plug the power cord into a 120V AC electrical outlet. This humidifier holds 1 Gallon of water and will produce up to 2.8 gallons of moisture over a 24 hour period. WARNING: DO NOT move the humidifier with water in tank or the humidifier base. The moving action of the water may activate the water tanks release nozzle and overfill the transducer cavity. This may cause the humidifier to function intermittently, or stop emitting mist altogether. Should this occur, simply remove the excess water from the humidifier base (see #3 under Daily Maintenance). IMPORTANT: If you do not plan to use your humidifier for two or more days, make sure any residual water is drained from the water tank and base to prevent any algae or bacteria growth in stagnant water. Make sure the tank is dry.

CLEANING/MAINTENANCE

USING A WATER PURIFICATION FILTER
The Water Purification Filter (UH325) is used to retain minerals in your water and provide a clean moisture output. The filter life is determined by the average daily use of your humidifier and the water hardness in your area. Areas with hard water will require more frequent replacement of the filter. It is strongly recommended that the filter be replaced every 1-2 months (depending on use), or when white dust is emitted from the unit. Please refer to the enclosed Humidifier Accessory Card included with your humidifier. It is recommended that you order your replacement filter at once so you will have a fresh filter available when necessary. 4. Re-install the Water Purification Filter (if being used) and replace the tank on the base. WEEKLY MAINTENANCE A. To Remove Scale 1. Repeat step 1-3 above. 2. Partially fill the base with Holmes Cleanse Clean model S-1710 (available by calling 1-800-546-5637) as instructed on bottle, or with one 8 oz. cup of undiluted white vinegar. Let solution stand 20 minutes, cleaning all interior surfaces with a soft brush. Gently scrub the area around the transducer with a soft brush. Be careful not to damage the sensor probe. Wipe the surfaces of the filter with the same cleaning solution. 3. Dampen a cloth with undiluted white vinegar and wipe out entire base to remove scale. 4. Rinse with clean warm water to remove the cleaning solution before beginning to disinfect the tank. B. TO DISINFECT TANK Do in area that will not be damaged by bleach. 1. Fill tank with 1/2 teaspoon of chlorine bleach and 1/2 gallon of water. 2. Let the solution stand for 20 minutes, swishing every few minutes. Wet all surfaces. 3.

CLEANING AND MAINTENANCE INSTRUCTIONS
Humidifiers provide comfort by adding moisture to dry, heated indoor air. To get the most benefit from the humidifier and avoid product misuse, follow all instructions carefully, specifically the operation, care and maintenance guidelines. Please note this is an electrical appliance and requires attention when in use. In addition, if you do not follow the recommended care and maintenance guidelines, micro-organisms may be able to grow in the water within the humidifiers tank and become airborne. The following cleaning procedures must be routinely followed in order to ensure proper, efficient operation of your humidifier. Proper maintenance is essential to the continued use of your unit and the avoidance of algae and bacteria build-up. DAILY MAINTENANCE 1. Before cleaning, turn power knob to the OFF position and unplug the unit. 2. Remove and empty the tank. Rinse thoroughly and wipe the inside of the humidifier tank with a clean, damp cloth. Refill with cool tap water. 3. If you are using a Water Purification Filter, remove the filter and thoroughly rinse the base. Place filter in sink as it will leak. To drain water from the humidifier base: grasp with both hands and tilt to the side, draining water into the sink. Do not place humidifier base in sink or place base directly under running faucet.
USING THE MIST VOLUME CONTROL
Turn the mist volume knob clockwise as far as it will turn to achieve the highest mist setting. In this setting, the humidifier will run constantly, and produce the greatest amount of moisture. To lower your desired mist level, simply turn the knob counterclockwise to choose your setting. Depending on the size of your room and your personal comfort, you will set your mist volume control at different levels. If condensation forms on your windows or walls, or your measured room humidity reads above 50% by use of a hygrometer, turn off your humidifier, or lower your mist volume control level.

Group Project 1
Bronwyn Hayworth October 20, 2004 Flow Visualization Prof. Hertzberg and Prof. Sweetman
A series of several hundred images was captured for the first group project of the Flow Visualization course. The intent of these images was to photograph the lofty, silky features of water fog created by an ultrasonic humidifier. It was hoped that these images would expose the ebbing nature and interesting vorticies of the fog. Unfortunately, this phenomenon was very difficult to capture and required a lot of patience and experimenting due to its highly three-dimensional nature. Many fruitless attempts were made at visualizing the thick fog as it initially poured from the spout of the humidifier. Thus, the challenge of flattening the flow while preserving its features was born. This flatter flow allowed the fog dynamics to be better captured by a camera. Figure 1 displays an image created by this technique. This is the final image chosen for Group Project 1.
Figure 1: Water fog flowing down an inclined plane.
The apparatus used to create the flow in this experiment was a Holmes Production Corporation Family Care humidifier (Model # HM-480) on flow setting II and the highest water vapor setting. As stated in lecture on October 11, 2004, an electric disk in the base of the humidifier is excited by high frequency and vibrates. The vibration leads to the creation of water droplets which emerge from the humidifier as water fog. The humidifier was placed on a short bench and a flat board was inclined at forty-five degrees to the ground to align with the outlet of the humidifier. This board was covered with a layer of black velvet to create a very rich and distinct background. A more complete depiction of the experimental setup is shown in Figure 1.

Figure 2: Flow Setup

From the spout of the humidifier, the fog was channeled to the top of the inclined plane and released through a triangular opening. The size of the triangular opening was approximately 3 cm at its peak by 20 cm at the base. A view of the triangular opening as examined from the base of the inclined plane is presented below. Water Fog from Humidifier

Figure 3: Channeling device (as viewed from the base of the inclined plane).
The basic flows observed were boundary layer effects of water fog as it flowed down the inclined plane. These effects were present on both the bottom and top surfaces of the fog as it interacted with the black velvet and the less moist ambient air. Each of these interactions created multiple flow dynamics, vorticies, and shear layers. The shear
layers seemed to roll up as the fog traveled down the inclined plane. The largest of these rollers are very evident in the image as areas of highlights. The fog on the leading edge of these vortex structures seemed to quickly evaporate as it was thrust into the less moist air. The evanescence of the fog was difficult to capture and never created the exact same flow pattern twice. By assuming that water fog is a saturated water vapor, or steam, at a temperature of 19.4 oC (67o F) and an ambient pressure of 84.34 kPa (12.23 psia) due to the altitude of approximately 1524 meters (5000 feet), Engineering Equation Solver (EES) can be employed to determine both the absolute viscosity (2.458 lbm/ft-hr or.001016 N-s/m2) and the density (998.27 kg/m3 or 62.32 lbm/ft3) of the fluid. The EES code is attached in the Appendix. These values can then be entered into the equation for the Reynolds number, Rex=Ux where U is the free-stream velocity x is the distance from the leading edge is the dynamic viscosity of the fluid is the density of the fluid Equation 1

The estimation of the free stream velocity of the water fog was.25 m/s (assumed to be constant in the direction of flow), and the value of distance from the leading edge varied from.05 m to.75 m. Thus, the Reynolds number for this flow ranged from approximately 12300 to 184000. The very large value of the Reynolds number at.75 m from the leading edge indicates probable turbulent flow in these regions. The spatial resolution of the image can be determined by examining the size of the smallest feature and comparing this to the size of the pixel used to capture the image. The resolution of this image is 28.346 pixels per centimeter or.0003527 meters per pixel. For this image, the flow dynamics are present on multiple scales including miniscule ones, such that it would be very difficult to spatially resolve the image more without the use of specialty equipment. The temporal or time resolution can be calculated by multiplying the velocity of the flow by the shutter speed. This value gives the distance traveled during the exposure and for this image is approximately.00417 m. Thus, because the value of the time resolution is greater than the value of the image resolution,
the image is not resolved well for time. A strobe or laser could be used to achieve better time resolution. Water fog created by an ultrasonic humidifier creates both the flow and the visualization technique used to observe the flow. A variety of lighting techniques were utilized to capture this image. The first component of the lighting was ambient light from two windows in my living room on October 17, 2004, a partially cloudy day, at 11:30 am. Each window was located approximately ten horizontal feet away from the flow visualization setup in the configuration shown in Figure 4. The second lighting component was an incandescent light situated almost directly above the velvet inclined plane. The 120 Volt, 150 Watt light bulb was covered with a stop blue CTO lighting gel and was approximately 5 vertical feet above the base of the inclined plane. In addition, the standard flash on the camera was used to further illuminate the image and provide a slightly less time resolved strobe effect. The camera and hence the camera flash were located approximately 3 vertical feet above the base of the inclined plane. Originally, the fog was white and gray in nature, however, with the application of the stop CTO blue lighting filter and the flash, the fog became bluish in color. I feel the application of these techniques increase the aesthetics of the image as a whole. The overall lighting setup is shown below, Ambient light from living room windows

Flash on camera

This image was captured with a 4.0 effective megapixel Nikon Coolpix 4300 digital camera on October 17, 2004 at approximately 11:30 am. The camera was in AutoFocus mode and the following settings and attributes were recorded.

Adobe Photoshop post processing was used to create an image that was cleaner and resembled the actual phenomena more closely. The filters, Auto Levels and Auto Contrast, were applied to achieve this balance. This image reveals some very interesting aspects of the flow phenomena of water fog. It displays the aesthetically beautiful flow and provides insight to boundary layer and shear layer dynamics between the fog, the flat plane, and the ambient air. It also presents an interesting commentary on how fog flows. I really like the composition of the image and the subtle vorticies evident in the highlights. I feel that these are also the most evident fluid physics present throughout the image as well. I would like to know more about what dictates the particular flow patterns I observed while capturing my images. It seemed like any change in the room environment could trigger a new flow pattern. The flow seemed particularly vulnerable to wind currents in the room and hence, extra precautions were taken to keep the ambient air as still as possible. My only problems with the image are that I wish it was more time and spatially resolved. I would like to use the high speed digital camera or a strobe light to attempt further imaging. However, despite these minor disappointments, I feel that I definitely fulfilled my intent both artistically and scientifically because I managed to capture an aesthetically striking
and physically intensive fluid flow. At the end of the first photo shoot, my images were so dismal that I almost judged this flow phenomenon impossible to image with my camera and setup. So, after days of work, when the imaging technique and images came together I was delighted. After further mastering the technique, I would like to work with different lighting filters to play with the illusion of warm and cold colors and their relation to the flow as suggested by Professor. Hertzberg. Another way to develop this idea further would be to either alter the flow patterns or the conditions.
