Abstract:
The results of theoretical and experimental investigations of the interaction of a gas jet with the surface of a viscous liquid are reported. Relations are derived for calculating the force exerted by the gas jet on the liquid surface. A dependence of the gas jet compression ratio in the nozzle outlet on the pressure in front of the nozzle is revealed. The values of the shape factor for the indentation formed by the gas jet on the surface of the liquid are determined for various diameters of the indentation and the distances between the outlet hole of the nozzle and the liquid surface. The theoretical conclusions formulated here are confirmed by the results of experiments.
