Features of the vapor formation process near a wall with a gas-droplet film cooling

Abstract

On the basis of available experimental data, we have performed an analytical study of the concentration of saturated vapor over a liquid film formed from droplets being deposited onto the wall of an adiabatic channel under gas-droplet film cooling. The analysis was carried out by varying the main parameters of the mixing jets, namely, the ejection coefficient, the concentration of the liquid, and the main-flow temperature. An approximating dependence for the concentration of saturated vapor in the presence of the liquid film is obtained, and the effect due to the flow nonisothermality is taken into account.
