CFD Validation for External Aerodynamics Part 1: Validating Component Analysis

Abstract

Validating external aerodynamics is often a complex process with more to consider than just obtaining the correct forces. This paper examines some of the issues related to the CFD modelling of car components such as wings, wheel assemblies and radiators. The types of mesh, choice of turbulence model and wall resolution (measured in terms of y+) are also discussed.
