Numerical Simulation of Filling Process in Large Steel-Ingot

A three dimensional incompressible gas-liquid two-phase flow model is proposed to accurately simulate the fluid flow of casting's mould filling process. The gas entrapment during mould filling is studied under different initial velocity and pressure conditions. The simulation results show that the velocity of change has a larger effect on gas entrapment, Initial velocity affects the ...
