Numerical simulation of engine cooling air flow of a road vehicle
Abstract
A modeling method for a heat exchanger is presented to predict engine cooling air flow rate. The comparison between calculations and experiments confirms accuracy of the modeling method. A modeling of vehicle body configuration is also discussed. It is found that precise modeling of engine room outlet configuration is important to improve estimation accuracy of engine cooling air flow rate. By taking into account these modeling methods, it is expected that the under floor flow field of a vehicle will be estimated accurately. This enables the study on flow interaction between engine cooling air flow and under floor flow numerically, which has been difficult to obtain physical image experimentally.
