Computational Fluid Dynamics (CFD) has witnessed significant advances in the last half decade making it applicable to a wide range of problems in the automotive industry. The advent of unstructured grid technology, improved physical modeling capabilities such as phase change, radiation etc. have contributed to the increased use of CFD in automotive applicatons. In spite of the use of unstructured grids, the area of under-hood airflow and thermal simulation still requires significant amounts of time for grid generation. The paper describes a new approach which uses a Cartesian based grid system that allows for generating completed under-hood meshes within 2-3 days. In addition, discussion about using a local (body fitted grid) model to address thermal issues is presented. This represents an optimal combination of tools to obtain useful informaton for making engineering design decisions.
