Abstract

The results are given of a theoretical and experimental investigation of the internal ballistics of a water cannon in which the water is set in motion by a shock wave and the firing of which involves cleaving of the water mass. The flow is calculated in the quasione-dimensional approximation by Godunov's method as generalized to the case of flows in which cleaving occurs [1]. The pressure in the barrel of the water cannon and the velocity of the jet at the nozzle exit were measured. Comparison of the experiment and theory demonstrated the admissibility of using the quasione-dimensional approximation and the model chosen to describe the cleaving of the water.
