Development of a rapid analysis system for pre-cooling process of large LNG full-capacity storage tank

In this paper, a quick analysis system for the pre-cooling process of large LNG tank was developed, based on ANSYS-Python. The system has the functions of establishing geometric model automatically, dividing grid automatically and solving automatically. Operation of the system is simple with high efficiency. Comparison with the field data results found that the quick analysis system is accurate to meet the requirements of engineering application. The quick analysis system is helpful to optimize the pre-cooling process and the structure of large LNG full-capacity tanks
