Wave phenomena upon interaction between water and high-temperature melt

A multiphase model for steam explosion is considered, with assumption of mechanical equilibrium between water and vapor phases in the mixture, but with non-equilibrium drag and heat exchange with high-temperature melt droplets taken into account. Governing equations are formulated and solved numeric...

Description
Summary:A multiphase model for steam explosion is considered, with assumption of mechanical equilibrium between water and vapor phases in the mixture, but with non-equilibrium drag and heat exchange with high-temperature melt droplets taken into account. Governing equations are formulated and solved numerically. Simulations of pressure waves following thermal interaction of hot melt and water-vapor mixture are presented, the structure of steam explosion wave is discussed.
