Turbulent heat-mass-exchange on the porous surface

Analysis heat and mass transfer moved for a porous surface and unisothermal terms at presence of transversal stream of gases. Carried out tests in the cylindrical graphite ducts. The walls of ducts were heated the currents of high-frequency to the temperatures of 2000 K. Inert gases: argon, nitrogen or helium was given through a porous surface. The streamlined surface was exposed to chemical erosion in a blast. Calculations in formulas, to expressed as criteria of similarity, satisfactorily comport, with results of experiments.
