Numerical Simulation of Boiling Flow in LNG Releasing Underwater Process

Abstract:

The boiling flow of LNG releasing underwater was numerically simulated by establishing liquid-liquid boiling flow transfer models and using multi-fluid model in FLUENT. The effects of quenching, average bubble diameter and turbulencemodel on the characteristics of hydrodynamic, heat and mass transfer processes were demonstrated. The results showed that in the progress of heat transfer between LNG and water, surface quenching makes an important role. The heat and mass transfer rate was influenced by valuing average bubblesdiameter. Because of per-phase turbulent flow making an equilibration important role in boiling flow process, turbulence models must be simulated respectively.
