Abstract
Effect of a difference in the thermal boundary condition is examined. DNS was carried out for constant wall temperature difference condition for Re_γ=180,395 with Pγ=0.71 to obtain statistical cross-correlation coefficients, turbulent Prandtl number, skewness factor and flatness factor. The obtained results are compared with those of DNS for the uniform heat flux heating. A large difference was obtained in the skewness and flatness factors of the temperature variance for the two thermal boundary conditions.
