LNG FPSO液舱内储液晃动特性的数值模拟
Numerical simulation of liquid sloshing characteristics in LNG FPSO containers
摘要
Abstract
The side pressure caused by the liquid sloshing, the gas-liquid mixing situation, the liquid sloshing amplitude and the pressure distribution in containers were studied in liquefied natural gas ( LNC) cryogenic large SPB-type storage tanks. The liquid sloshing characteristics in two-dimensional membrane SPB-type tank were simulated based on VOF (volume-of-flu-id) model. The simulated results were compared with the experimental data. The results show that the simulation data agree well with the experimental data. The sloshing amplitude is related to the initial velocity, the greater the initial velocity, the more violent the sloshing. At the same time, the sloshing induced by different filling rate of liquid is also different, the greater the filling rate, the smaller the sloshing amplitude, which helps to reduce liquid sloshing. It is beneficial to restrain sloshing through installing baffles reasonably.关键词
