Turbulent Heat Transfer

Simultaneous measurement of temperature and velocity was achieved using laser induced fluorescence and particle image velocimetry. The following animation depicts velocity and temperature on a symmetry plane in the stagnation region of the plane impinging jet. The counter-rotating vortex pairs appeared near the wall sweeps thermal boundary layer and ejects heated fluid, displayed in red color. This work was performed in Keio University in 1992.
