Unsteady RANS Simulation of High Reynolds Number Trailing Edge Flow

Unsteady vortex shedding at a trailing edge may cause pressure fluctuations and strong tonal noise which can have important consequences to the performance of marine and aeronautical type lifting surfaces. This paper presents data from unsteady RANS simulation of high Reynolds number trailing edge flow. It aims to identify and quantify dominant features of the trailing edge flow field over a tw...

Simulation of High Reynolds Number Vascular Flows

While much of the hemodynamics in a healthy human body has low Reynolds number, resulting in laminar flow, relatively high Reynolds number flow is observed at some specific locations, which can cause transition to turbulence. (The term “turbulence” refers to the motion of a fluid having local velocities and pressures that fluctuate randomly.) For example, the peak Reynolds number in the human a...

Direct Numerical Simulation of the Wake Flow Behind a Cylinder Using Random Vortex Method in Medium to High Reynolds Numbers

Direct numerical simulation of turbulent flow behind a cylinder, wake flow, using the random vortex method for an incompressible fluid in two dimensions is presented. In the random vortex method, the primary variable is vorticity of the flow field. After generation on the cylinder wall, it is followed in two fractional time step in a Lagrangian system of coordinates, namely convection and diffu...
