Turbulence Generators and Turbulence Structure

Turbulence in the flow impacts the peak pressure on buildings by more than 100% in certain locations, and in the same way, it impacts many phenomena in several industrial applications. Understanding turbulence will improve the process of computing peak pressure on buildings. In this work, methods to identify the turbulence structure are reviewed. Then, Q-criterion, vorticity in z, and magnitude of vorticity are used to evaluate the turbulence structure developed using inflow turbulence generators based on random Fourier method (NSRFG and CSDE) and precursor method. Iso-surfaces and contours on planes are used to visualize the turbulence structure.
