A turbulent immersed air wall jet on a burning graphite surface

The turbulent boundary layer in an immersed air jet traveling along a burning graphite wall is analyzed. In order to study the heat and mass transfer and the friction in the boundary layer, a method of calculation based on the solution of the integrated energy and momentum relations is employed, allowing for the conservative properties of the turbulent boundary layer at the wall 1].Notation x longitudinal coordinate - y transverse coordinate - s height of slot - thickness of boundary layer - * displacement thickness - ** momentum-loss thickness - velocity - j transverse mass flow (flux) - density - T temperature - i total enthalpy - temperature factor - ₁ enthalpy factor - k reduced concentration of the i-th component - tangential stress - b permeability parameter - C₁ form (shape) parameter - dynamic viscosity coefficient - c _f friction coefficient - relative friction coefficient Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 1, pp. 60–67, January–February, 1971.
