Turbulence statistics of a channel flow with strong wall heating at Reynolds number of 14, 000 were investigated experimentally. The statistical quantities up to triple correlations were estimated, using data measured by a single component LDV. The wall temperature varies up to 1000 K. Rms values of streamwise and cross-stream velocities and their correlation decrease in the thermal boundary layer except near the wall. Near the wall, the ejection of low-speed fluid outward from the wall is intensified due to thermal expansion, and it cancels the decrease in statistical quantities. As a result, the statistical quantities do not vary apparently.
