Voxel based simulation is very convenient at the early stages of a product design because the simple block approximation of a shape can realize automatic and robust mesh generation. However, the voxel method is not capable of simulating the characteristics of flow and expressing the detail shapes less than the voxel size. Therefore, the relationship based on an experimental data, which reflects the flow characteristics, is often incorporated into the simulation as boundary conditions. For accurate flow simulation in an engine bay, the satic pressure drop caused by heat exchanger should be taken into account in governing equations. In this paper, the modeling of pressure loss at the heat exchanger on the voxel method is proposed. Incompressible flow around a heat exchanger was calculated using the present method as verification. It was found that the proposed method could accurately predict the pressure drop and flow field.
