Mathematical Modeling and Numerical Analysis of Efficiency of Surface Film Coolingin Supersonic Flow Dispersion

The article provides a mathematical model and results of computational investigations into the effect of the inertial deposition of particles of condensed phase on the efficiency of film cooling of surface in supersonic flow dispersion. The authors determine a possible realization of Leontyev paradox in adiabatic surface area, which consists in achieving protected surface temperature less than that of cooler in permeable area of protection creation.
