Abstract

The velocity profile in the streamwise direction proposed by Hatta and Nozaki is compared with the other ones by using the mean width of the jet analogous to the displacement thickness of the boundary layer. In order to refer the experimental results and the different solutions of a free jet to each other, the constant contained in the eddy kinematic viscosity is also compared with the spread parameter contained in the solutions proposed by Gortler.
