Investigation of compactness of free unsubmerged jets

Abstract

When breaking rocks with a water jet, the flow due to the potential energy of pressure in the hydromonitor at the exit of the nozzle acquires kinetic energy and, freely interacting with air, is gradually aerated, which leads to the dispersion of the jet. Since the efficiency of the destruction process depends to a large extent on the compactness of the jet, the study of compactness and factors determining it is of practical interest.
