As experimental study of a two-dimensional incompressible constant-pressure turbulent boundary layer has been made to determine the effects of free stream turbulence on heat transfer and skin friction coefficient. In the wide range of pitch・diameter ratios of turbulence grids, the mean flow measurements and some turbulence measurements were performed. The results of the measurement clearly indicate that the increase of heat transfer rate with the free stream turbulence intensity is affected by the pitch・diameter ratios of turbulence grids. The experimental equation expressed by the diameter of turbulence grids, the pitch・diameter ratio and the turbulence intensity of free stream also agreed well with the results obtained by previous workers.
