Abstract

Measurements of the correlation of fluctuating velocities parallel and normal to the freestreamwise direction, as well as the mean velocity and turbulent intensity of velocity fluctuation parallel to the freestreamwise direction, in the flat-plate turbulent boundary layer with mass addition and a diffusion flame have been made using a laser Doppler velocimeter. The profile of the correlation has two maxima and one mimimum and becomes negative in the airstream side of the flame zone. This typical profile of the correlation qualitatively corresponds to the profile of the mean velocity gradient normal to the freestream direction in the whole region of the boundary layer near the leading flame edge. In the downstream region, the profile of the correlation does not correspond to the profile of the mean velocity gradient at the flame zone. These results suggest that the correlation can be treated as that of an ordinary shear-generated turbulence in the whole region of the boundary layer except near the flame zone.
