Development of Underbody Aerodynamic Simulation Using Automatically Generated Tetrahedral and Prismatic Cells 2001-01-0704

The aerodynamic characteristics of the vehicle underbody are one of the critical components to achieve efficient fuel-economical vehicles. On the other hand, computer memory and time make it difficult to make the complex geometry of the underbody of an actual vehicle including the engine room. In this paper, we have investigated a new CFD analysis method using the automatic tetrahedral/prismatic cell generation tools for the analysis of an underbody flow. The CFD analysis results are compared with experimental data. This new method also contributes to reducing the development term of the aerodynamics characteristics with underbody.
