Vogel, J.C., Eaton, J.K., “Heat transfer and fluid mechanics measurements in the turbulent reattaching flow behind a rearward facing step”, Report MD-44, Thermosciences Div., Dept. of Mechanical Engineering, Stanford University (1984).

Problem Description

The experiment of Vogel, et al. (1984) is used to verify the accuracy of the turbulence flow modeling capabilities of Autodesk Simulation CFD. The aim is to accurately predict the location of flow reattachment downstream of the step.
