Numerical Simulation for Distribution of Void Fraction in Water Model of Continuous Casting Mold

Abstract:

According to the distribution of void fraction in water model of continuous casting mold, the influences of bubble size, water flow rate, and air flow rate on distribution of void fraction were studied by quasi single-phase model. The results indicated the distribution of void fraction generally showed a garlic shape. Both of the bubble diameter and the water flow rate have great influence on the distribution range of void fraction. Specifically the distribution range of void fraction increased with water flow rate and decreased with bubble diameter. And the gas flow rate has little effect on the distribution range of void fraction. The experiment results verified the authors model.
