| Abstract: | Taking 50000m3 type BSindependent liquid tankSas the research object, the CFD numerical simulation method was adopted to establish the mathematicalSheat transfer modelSof typeSB liquid tank and determine theSboundary conditions; then, differentSinsulation thickness,Sthermal conductivity of insulation material, cargo tankSexternalSenvironmentStemperature, adiabaticSlayerSdamage and other factors effects on theSliquid cargo tankSheat leakageSand evaporation rateSwere analyzed. Finally,Sthe changes law of theSliquid cargo tankSheat leakageSand evaporation rate which were affected by cargo tankSexternalSenvironmentStemperature, adiabaticSlayerSdamage and so on was obtained, which had important implications for innovation and design of the LNG carrier maintenance system. |
