Analysis of Evaporative Phase Transition in LNG Tank under Sloshing Conditions
With the green and clean benefits of natural gas,the market demand is soaring.In order to ensure the operation's safety of the liquefied natural gas(LNG)carrier,it is particularly important to analyze and calculate the daily evaporation rate of the LNG cabin under different operating conditions.The LNG phase transition evaporation state of liquid cargo tank on LNG carrier is studied by FLUENT software in the sloshing state.The results show that the degree of superheat between the inner wall and the loading rate of the tank can greatly affect the evaporation state of LNG,which can quickly enter to the stable evaporation stage,and its evaporation mass flow rate tends to be stable in time.The simulation analysis method introduces the sloshing variable factor for the evaporation calculation of LNG cabin,also provides references for related ship research and development.
