Abstract

The attached eddy hypothesis is used to develop a means of generating synthetic turbulent boundary layers. Fluctuating velocity fields are created from simple vortex shapes using the Biot-Savart law. These are superposed with mean velocity profiles from experiment or RANS to create boxes of data which can be fed in through the inflow plane of a simulation. This provides realistic time varying inflow data. The method is computationally inexpensive compared with other synthetic inflow generation methods. Two flows are investigated using this approach. In the first, detached eddy simulation is used to compute normal and angled injection of helium into supersonic turbulent crossflows at Mach num..
