摘要

The experimental data on mass transfer during ethanol evaporation and combustion in the boundary layer on a horizontal surface are analyzed. The effects of a barrier (up to 15 mm high), external turbulence (up to 26 %) and air velocity (up to 58 m/s), close to the flameout velocity in the boundary layer, are considered. The review is supplemented with experimental data for converging and expanding channels. The conclusion that the limits of mass transfer intensity during combustion are determined by the regularities for laminar and turbulent boundary layers on a smooth impermeable plate during evaporation without combustion is confirmed.
