Current consumers and codes of standards for automobiles demand high-performance heating, ventilation, and air conditioning systerns for automatic control of the vehicle's interior climate, comfort, and visibility. Thus, optirnurn interior climate control has become viewed as an important quality factor for market competitiveness. To date, the design of such ventilation / defrosting systerns has utilized 'trial-and-error' and 'prior experience' techniques. But development and production eficiency has generated a strong interest in developing more sophisticated design tools such as computational fluid dynamics (CFD). For this purpose a joint experimental and numerical study was undertaken. Before relying upon CFD for prototype design testing, the computational models must be tuned, tested, and validated. This is especially important when CFD is used in a competitive industry such as the automobile industry. To do this, an extensive and accurate experimental data set of relevant quantities (such as the velocity field, turbulence field, temperature field, etc.) is necessary. This comprehensive investigation was divided into two parts. First, the three dimensional defroster flow field was measured using LDA in an actual automobile. Second, LDA and infrared thermography was used to map the flow and temperature fields for a two dimensional jet impinging upon a slanted plate -- a simplified representation of a car defroster geometry.
