Numerical Simulations on a High-Temperature Particle Moving in Coolant

This study considers the coupling effect between film boiling heat transfer and evaporation drag around a hot-particle in cold liquid.Taking momentum and energy equations of the vapor film into ac-count,a transient single particle model under FCI conditions has been established.The numerical simulations on a high-temperature particle moving in coolant have been performed using Gear algorithm.Adaptive dy-namic boundary method is adopted during simulating to matching the dynamic boundary that is caused by vapor film changing.Based on the method presented above,the transient process of high-temperature particles moving in coolant can be simulated.The experimental results prove the validity of the HPMC model.
