Abstract : On the basis of the approximate boundary-layer theory an investigation is made of the problem of turbulent mixing of two uniform flows of a compressible fluid for Prandtl numbers different from one with particular attention to the temperatures and velocities of the mixing flows. The equations of turbulent mixing are reduced to the equations of laminar mixing using some new independent variables. It is shown that introduction of these new variables permits separation of the boundary-value problem for flow in the mixing zone, which involves certain mathematical difficulties, from that of calculating temperature and velocity profiles for actual cross sections, which is not difficult mathematically but requires the use of empirical quantities.
