Abstract
The objective of this paper is to develop an analytical approach to compute cooling airflow at any particular fan and vehicle speed condition in a vehicle from a minimum number of CFD (Computational Fluid Dynamic) simulations or test runs using fan performance data. The vehicle system resistance is used with fan performance curves to find the cooling airflows of the vehicle. Fan performance curves at any fan speed are computed using fan laws and the CFD simulations are used in computing the system resistances at a particular vehicle speed. The paper outlines the prediction of system resistances at other vehicle speeds and its use in computing the cooling flows at those speeds. The approach is validated using CFD for different combinations of vehicle and fan speeds.
