“…But major drawbacks of the reverse cycle method applied in a car are the possible water condensation or frost formation on the IHX during defrost, which supports flash fogging when switching back to heating mode (Peters, 1972). Further, the cold air exiting the IHX can not be blown into the vehicle cabin without dramatically reducing thermal comfort.…”

“…Preliminary results indicated that apparent surface reflectance measurements were highly sensitive to the presence of condensate on the surface. Slow fog (condensate) build-up and flash fogging on the windscreen can occur for certain vehicle conditions [1]. Both conditions can severely effect passenger safety and vehicle operation [2].…”

A novel optical technique to measure condensate thickness on surfaces has been developed. Surface reflectance measurements in the far-infrared spectrum correlate well with the quantity of condensate mass on the surface. An empirical relation has been developed that provides an optical measurement of the local condensate thickness from 0 to 5 µm on a reflective surface as a function of time and location. Measurements of the mass transfer coefficient in a two-dimensional wall jet flow with the optical infrared reflectance technique agree with steady-state mass transfer measurements for the same flow. Mass transfer results also agree with those reported in the literature for similar flows.

Road visibility in passenger vehicle is of major concern for the car manufacturers and safety design engineers. Water film (Fog) that forms on the windshield during winter times would reduce and disturb the driver’s visibility. Extreme weather condition can make a difference while driving. One may experience the wide range of challenges during driving. The factors which mostly affected the visibility can be rain, fog, ice, snow, dust, etc. Due to such factors, it becomes very tough for driver to have a clear view of front side. Rear view is possible with the help of left and right view mirror fitted outside the front doors. Visibility of rear view mirror depends upon the visibility of the front side window glasses. Driving through rain, produces more challenging situation when water droplets on outsides surface of front window glass obstruct the vision. This problem becomes more dangerous when light gets scattered through water droplets and obstruct the vision during rainy night. The main objective of this work is to find the possible solution for removing the fog from a specific area of front and rear windshield to have a clear view to avoid the accidents. In the present work, hot water and silicon fluid utilized to impinge on the front and rear glasses with the help of converging nozzle and fluid inside the two windshields. The various combination of outlet water and silicon temperature is used for obtaining maximum clearing area. Computer simulated results are verified with the experimental results.
