Heat Exchanger Simulation in Wind Tunnel Models

Airflow characteristics of simulated heat exchangers for wind tunnel models are determined for various situations. These situations include inclining the core at various angles to the flow direction, simulating the exit ducting and turning vanes as used by many open wheeled racing series, such as CART's Champ Car series or FIA's Formula One. The characteristics determined include the blockage and the estimated heat rejection of the radiators. The Results of this investigation show that perforated plates are adequate for heat exchanger simulations in wind tunnel models.
