Abstract

The flow in ventilated rooms is often not fully turbulent, but in some regions the flow can be laminar.
Problems have been encountered when simulating this type of flow using RANS (Reynolds Averaged Navier-Stokes) methods. Restivo carried out experiment on the flow after a backward-facing step, with a large step.
