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.
