제목 Modeling and simulation of LNG fueled vessel for bunkering system reflecting CFD result
초록 LNG, a cryogenic liquid material at about -160 °C, which serves as fuel is stored and discharged in LNG Fueled Vessel (LFV). The LFV is refueled periodically from the LNG Bunkering Vessel (LBV). During the LNG refueling process, the following phenomena occur in LFV: 1) Heat input from the surrounding 2) Volume change by the incoming LNG 3) Pressure change due to the exhaust NG 4) Convection of the vapor and liquid parts inside the storage tank 5) Boil-Off Gas (BOG) generation by rollover. Similar to general process design, the amount of gas to be treated for securing safety is estimated by the process simulation. Also, optimal control philosophy might be designed based on the understanding of sudden dynamic change of thermodynamic properties. However, it is challenging to predict the above phenomena using analytic solutions or process simulation software.
To overcome this limitation, CFD simulation was conducted to investigate dynamic phenomena, such as variation of the pressure and heat distribution, appearing in bunkering process in advance. And the results were employed to develop dynamic simulator (using gPROMS) for bunkering process simulation.
