Abstract
A visualization system was developed for the analysis of engine compartment flow. This system consists of mesh generation, calculation, and animation system. Analytical mesh was generated by a new method applying STAR-CD. This method made it possible to accurately define the object shape easier than conventional multi-block method. Fan model was developed by measuring the axial and rotational com-ponent of flow velocity behind fan blades. As the results, it was found that fan rotation has large effect on the engine compartment flow especially under low vehicle speed condition.
