This paper reports a numerical investigation of the incompressible flow over a 25◦ backward-facing ramp. Different approaches and flow solvers are applied.

Abstract

This paper reports a numerical investigation of the incompressible flow over a 25◦ backward-facing ramp. Different approaches and flow solvers are applied. URANS simulations have been performed by the CIRA-developed UZEN and the Open-FOAM codes. The CIRA-developed flow solver Spark-LES together with OpenFOAM have been applied to resolve the turbulent structures on a simplified geometry and a reduced computational domain resembling the separated flow region over the ramp. The activities are being performed in the framework of the CIRA-funded project SHAFT. The final aim is to investigate the control of the separation phenomenon by means of zero-net mass flux actuators. © 31st Congress of the International Council of the Aeronautical Sciences, ICAS 2018.
