LES modeling of the turbulent flow over an Ahmed car

  • Conference paper
Direct and Large-Eddy Simulation VIII

Part of the book series: ERCOFTAC Series ((ERCO,volume 15))

Abstract

The Ahmed body car is a semi-rectangular vehicle with a rounded front part and a slant back. Flow over this generic body reproduce the basic fluid-dynamics features of real cars with a typical fastback geometry and its simplified topology allows easy comparisons between experimental and numerical works.
