摘要: Natural convection in a liquefied natural gas storage tank, which is caused by the heat absorption from surrounding environment, studied numerically solving conservation equations for mass, momentum, and energy with commercial computational fluid dynamics code, FLUENT. The present numerical results show that interfacial transfer rate, directly related to boil-offgas generation strongly depends on liquid-solid contact area. contribution of rate vapor region negligible compared liquid region. effects external coefficient, tank size, shape flow temperature fields flux are quantified.
