Equilibrium temperature of gas mixture in the jet /film/ cooling of a plate

The dependence of the equilibrium gas-mixture temperature on the parameters of the intermingling fluxes in the jet cooling of a plate is studied both experimentally and theoretically. Results show that the economy of jet cooling is determined primarily by the flow rate of the cooling air and the velocity and temperature ratios of the mixing fluxes. In addition, it is found that disregarding the thermal conductivity of the material may introduce pronounced distortions in the value of the equilibrium temperature.
