Gas-Liquid Mixture Flowing Out of a Hole under Falling Pressure

Abstract

An effective and reliable mathematical model is the effective method for calculating the cells' parameters, allowing to calculate the hydrodynamics and characteristics of heat and mass transfer of two-phase vapor-liquid flows with non-condensing gases in the heated channels of power installations in emergencies, is developed. The effects of the influence of non-condensing gas dissolved in water on the hydrodynamics and heat exchange in the two-phase flow, accompanied by a decrease in pressure, starting from the steady state of the circuit of power plants at nominal parameters have been studied. A marked effect of the separated non-condensing gas from the liquid on the flow hydrodynamics during the pressure drop is shown.
