Numerical simulation research of instantaneous gale environment on LNG storage tank based on CFD
In order to analyze the pressure distribution and wind field characteristics of the windward and leeward sides of the storage tank under different gale speeds,the k-ε turbulence model was used to establish the instantaneous gale environment model of the Liquefied Natural Gas(LNG)tank area.The CFD software FLUENT was applied to simulate the wind environ-ment of LNG storage tank,and the analysis module of the software was used to generate the pressure cloud map and wind speed vector map of storage tank.The results show that the bearing pressure of LNG storage tank on the windward side is higher than that on the leeward side,and the pressure presents a symmetrical distribution.The front end and the two sides of storage tank are prone to generate the gas vortex,but the overall speed curve is relatively regular,without the chaotic and com-plicated speed curves.The research results provide theoretical reference for the enhancement of disaster resilience of LNG sta-tion and the planning of emergency evacuation path in extreme gale weather,and have important guiding significance for the safety construction of LNG storage tank area.
