説明
Full measurements of thermal field were made for a turbulent flow of air in the entrance section of a two-dimensional curved channel. The wall heat flux develops more rapidly than the mean temperature distribution, decreasing and increasing on the inner and outer walls, respectively. Locations at which the mean temperature gradient and the radial component of turbulent heat flux become zero do not coincide in this case, and the eddy diffusivity of heat becomes negative in a region of about 20% of the channel width. In the vicinity of the wall, the temperature fluctuation intensity normalized by the friction temperature is not affected by the wall curvature, whereas the cross correlation coefficients between velocity and temperature fluctuations, the skewness and the flatness are appreciably affected by it. The triple correlations relating to the transverse diffusion decrease and increase remarkably in the inner and outer sides of the channel, respectively.
