Numerical Simulation of Three Dimensional Engine Compartment Air Flow in FWD Vehicles

Numerical analysis of flow around the front end and in the engine compartment of FWD vehicles in three-dimension is presented. Finite - Volume Method is used for numerical integration of Navier-Stokes equations, incorporating k-ε model for turbulence.

This method proved to be effective tool, showing good agreement of volume flow rate through radiator with experiments. Application of this method from the early stage of vehicle development contributed to significant saving of development term.
