Numerical Research on Two-phase Flow and Heat Transfer Characteristics on a Liquid-Reactor Experimental Model

The MUSIG model and the mono-disperse model are used to simulate the two-phase flow and heat transfer phenomena in a liquid-reactor experimental model.In simulation with MUSIG model,bubbles in the model is divided into 5 groups and these groups are used to analyze the bubble distribution and change in the flow.Luo and Svendsen model and Prince and Blanch model are used to describe the break and aggregation between bubbles.In simulation with mono-disperse model,bubbles in the liquid-reactor model is considered to have only one size,so the break and aggregation between bubbles are not in consideration.The results of simulation with the two models are compared,and the MUSIG model comparatively tallies with results of experiment.
