Fluorescent luminous microsphere plastic particles Lumisis Marker® is used as tracers to visualize the turbulent water flow. And velocity field is calculated by tomo-PIV method to obtain the velocity gradient tensor. The vortex structures are identified by Q-criterion and the vortex sheet structures exist surrounding them. We also report the applicability of Lumisis® to air turbulent flow by UV laser illumination. The flow field is visualized by tow colors (red and green) and the mixing process is visualized for the first time.
