The purpose of this study is to develop and demonstrate the techniques needed to perform a computational analysis of a windshield de-icing problem. A numerical model of a simplified test vehicle configuration has been built which includes the passenger compartment air, the windshield and the ice/water layer. A transient analysis was performed for conditions for which cold room test data is available. The results of the numerical simulation show very reasonable agreement with the test data.

The paper describes a predictive tool for the determination of air and coolant temperatures and heat exchange resulting from the operation of heat exchangers, e.g., radiator or air-conditioner condenser in the underhood of automotive engines. The paper describes a detailed computational model where both the fluid streams are numerically solved and the phase change of the refrigerant is taken into account in a condenser simulation. An actual underhood simulation with interactions with a radiator is presented. A numerical simulation for a condenser is also presented. Reasonable agreement is shown with the test data.
