3 D-3 C visualization of velocity gradients and coherent structures in free shear turbulent jets by TRSS-PIV and volumetric PIV

Abstract

Instantaneous 3D-3C visualization of the velocity, velocity gradients, vorticity, strain rate and pressure are obtained with near Kolmogorov scale resolution for a free shear turbulent jet. These 3D structures are calculated from 3D-3C velocity fields obtained with two volumetric measurement systems that are compared to each other. One is a Time Resolved… (More)
