Особенности пульсирующих струй жидкости высокой скорости

Abstract

The processes in a pulse generator of liquid jets were investigated in acoustic and gas-dynamic settings. In the acoustic setting a one-dimensional problem was considered without taking into account the piston movement and the jet outflow. In the gas-dynamic setting a one-dimensional and axisymmetric problem was solved numerically with taking into account the piston movement, jet outflow and liquid cavitation. The results of calculations for different models of fluid motion were compared. The appropriate conclusions were made. It was shown that the jet velocity pulsations were related to the wave processes in the installation.
