An evaluation of a conservative fourth order DNS code in turbulent channel flow

Direct Numerical Simulation (dns) of Turbulent Flow over Wavy Surfaces

Abstract. The present study adresses the turbulent flow over a wavy surface by direct numerical simulation (DNS). Compared to classical channel flow the wavy surface structure adds a degree of complexity to the flow by inducing streamline curvature, flow separation and flow reattachment, thus leading to flow situations which are often present in relevant technical and geophysical applications. ...

Direct Numerical Simulation of a Sonic Round Jet in a Turbulent Supersonic Cross Flow

A direct numerical simulation of a round under-expanded sonic jet in turbulent supersonic cross flow has been carried out. The objective is to investigate the mixing mechanism which occurs downstream the jet by use of a passive scalar variable. The Navier-Stokes equations in the cylindrical geometry are solved by use of multiblock overlapping meshes. The method has been validated with a laminar...
