Guidelines for Aerodynamic Assessment of Mass-Produced Cars and Light-Duty Trucks Using Computational Fluid Dynamics
This document outlines general requirements for the use of Computational Fluid Dynamics (CFD) methods for aerodynamic simulation of mass-produced cars and light-duty trucks. The document provides guidance for aerodynamic simulation with CFD methods to support current vehicle characterization, vehicle development, vehicle concept development and vehicle component development. The guidelines presented in the document include Navier-Stokes and Lattice-Boltzmann based solvers.
Rationale: Increased use of CFD in the development of vehicles means that it would be useful to outline best practice in this field. This will ultimately increase development efficiency and improve products (including with regard to fuel consumption and emissions). The proposal to initiate this document has been initiated following discussion and consensus at meetings of the Road Vehicle Aerodynamics Forum Committee.
