Oscillographic studies of the dynamics of unsubmerged water jets

Abstract

Experimental study of the dynamics of free water jets that meet a rigid barrier on their way is very important for the accumulation of experimental data contributing to the establishment of a number of regularities necessary for the creation of the theory of hydraulic stripping of coal from the massif at hydromechanization of coal-mining works.Of primary importance in such experiments is the identification of the jet impact force on the barrier depending on the water pressure in the jet-producing device, on the diameter of the nozzle outlet and the distance from the latter.
