Abstract

The objective of this study is to investigate the phenomena that occur in the course of energy injection into water at an extremely high rate. In this study energy was injected via the powder explosion. In the course of this study a numerical model was constructed and used for process investigation. The model describes powder combustion, energy exchange between combustion products and the water load, formation of the shock waves in the water and superposition of waves. It was assumed that powder combustion is a stationary process, and the description of this process was used to determine the variation of the pressure exerted on the water. The 1D space approximation was used for description of the dynamics of the water motion. The velocity and pressure fields were determined for a fixed instant of time. The characteristic method was used to relate the velocity and pressure distributions in the instants t and t+Δt. The pressure, velocity and density fields in the course of slug formation were calculated and used to evaluate the design characteristics of the device for water acceleration termed the water cannon.
