Parametric Study on Automotive Windshield Defrost Pattern using CFD 2003-01-1078

Prediction of automotive windshield defrost pattern using CFD is becoming increasingly important as a complement to cold chamber and field testing to achieve the improved windshield defrosting performance while reducing vehicle development time and cost. Although CFD simulation is popular and convenient, the efficiency and accuracy of simulation somewhat strongly depend on the simulation parameters such as choice of computational grid system, boundary conditions handling, flow consideration including turbulence model, and so on. In this investigation, parametric study on automotive windshield defrost pattern using CFD was performed about simplified passenger compartment. The objectives of this study are to examine the effects of each para-meter and derive the optimized simulation methodology of windshield defrost pattern.
