Experimental study of high-speed gas-film flows in curvilinear channels with drop injection of liquid

The paper investigates the local thickness distribution of a wall liquid film in a curvilinear channel. The research technique on experimental water-air stand with a curvilinear working channel is described. The results of measurements of the local thickness of the liquid film on the upper and lower walls of the channel for two flow velocities are obtained at various flow rates. © Published under licence by IOP Publishing Ltd.This work was supported by the grant Russian Foundation for Basic Research No. 17–38–50069
