Velocity-temperature correlations in a strongly heated channel flow were investigated experimentally by a LDV and a resistance thermometer. The wall heat flux is varied up to 50,000 W/m2 with reference mean-velocity of 15 m/s, and then, the wall temperature reaches up to 1,000 K. The results show that the ejection fluid motion is intensified by the strong heating near the wall increasing the turbulent heat flux from the wall. The intensification of ejection motion balances the destruction of turbulent heat flux. Then, the overall turbulent heat transfer does not change clearly.
