Abstract

The paper is devoted to numerical modeling of the dynamics of a submerged jet, being formed at water outflow from a high-pressure vessel into surrounding limited volume stationary medium of the pit. Features of high-speed submerged jet formation and pressure wave propagation in pit were defined. The initial pressure at the vessel was equal 150 MPa, the initial temperature—150°C. It was shown that under these conditions the system equilibrium pressure corresponds to 200 standard atmospheres and being settled within \(80\;{\text{ms}}\) from the beginning of liquid outflow from a vessel. It was shown that the maximum hydrodynamic load constituted 2.25 MN, which is 16 times higher than the force in the case of a jet flowing into a space filled with air.
