Abstract

Authors: Giovanni Lombardi, Enrico Cardile, Luca Caldirola, Stefano Carmassi

Keywords: CFD, underbody aerodynamics, exhaust geometry, automotive

The document examines how different discharge surface shapes affect vehicle aerodynamics through experimental and numerical analysis. The research demonstrates that exhaust geometry is important for drag, vertical load, and balance calculations. Flow separation behavior differs significantly across geometries tested.
