Airflow Over an Ahmed Body
Model ID: 8565

The Ahmed body represents a simplified, ground vehicle geometry of a bluff body type. Its shape is simple enough to allow for accurate flow simulation but retains some important practical features relevant to automobile bodies. This model describes how to calculate the turbulent flow field around a simple car-like geometry using the Turbulent Flow, k-epsilon interface. Detailed instructions guide you through the different steps of the modeling process in COMSOL Multiphysics.
