Abstract
The paper examines heat- and mass-transfer processes between a liquid film and a turbulent gaseous boundary layer behind a shock wave. The study is important for understanding the mechanism of heterogeneous detonation in the liquid-film gaseous-oxidizer system. Under the conditions of a tubulent gaseous boundary layer, large-scale disturbances appear on the gas-liquid interface and the surface of the film becomes an irregular structure of waves and splashes, from whose crests drops of liquids are detached. The drops penetrate into the boundary layer and are carried away by the high-velocity gas flow downstream. Experiments show that in the presence of high dynamic velocities of the gas, the mass carried away by the drops is larger than the mass carried away by evaporation. At the present time, there is no justification for neglecting, as in the detachment of drops.
