| Abstract: | Temperature measurements at different vertical locations in a turbulent boundary layer over a heated plate in a wind tunnel have been carried out by using hot wire anemometer. The extended self-similar scaling law and the hierarchical structure model of temperature structure function, as well as their relations with the homogeneity of mean flow field of shear turbulence have been investigated experimentally. |

| Keywords: | temperature wall turbulence extended self-similarity hierarchical structure model |
