turbulence; quasi-two-dimensional jet


We experimentally investigated the dynamics of 3D vortex structures of a quasi-two-dimensional turbulent jet. The time-resolved tomographic PIV technique (with repetition rate up to 10 kHz for 1 Mpx CMOS cameras) was used to measure subsequent 3D velocity distributions. This work focuses on characteristics of 3D vortex structures in the flow. It was found that in the flow of quasi-two-dimensional turbulent jet two types of coherent vortex structures are generated: large-scale quasi-two-dimensional vortex structures that are a consequence of the development of the Kelvin – Helmholtz vortices and secondary vortex structures, which are formed due to interaction between the Kelvin – Helmholtz vortices and the channel walls.
