In this paper we introduce a novel method for calculating 3D flow through the underhood compartement of a vehicle. The method is based on the system of Euler equations, which are numerically solved by a finite volume approach. The total number of finite volumes is very low (<1000 cells) The applied numerics are calibrated to recapture a preceding detailed computational fluid dynamics (CFD) simulation. This calibration is established by two sets of factors. The main advantage of the present approach is that the calibration factors can be inter- and extrapolated between different CFD simulations.
