In the previous report, we proposed a method to calculate the development of the incompressible turbulent wake close to a flat plate. The calculated results were compared with experimental data in which the wake started from the turbulent boundary layers on both sides of a thin flat plate. The agreement between the calculated and the experimental results was very good, and we can conclude that the diffusion phenomenon of the turbulent near wake has been made clear both qualitatively and quantitatively. In that case the shape parameters of the boundary layers at the trailing edge of the plate were all equal to 1.45. Here in this report, we extend the previous method so that we can study the effect of the boundary layer profile and that of compressibility upon the development of the turbulent wake close to a flat plate. The calculated results show that the wake profiles is dependent on the boundary layer profile and compressibility. The agreement between the calculated and the experimental results is excellent.
