Optimization and simulation experimental research on sub and mother tanks of supercritical LNG railway tanker
In order to solve the difficulty in designing sub and mother tank structure of super-critical LNG railway tanker,as well as the difficulty in determining the volume and number and the arrangement of sub tanks,a completely model of supercritical LNG railway tanker and structur-al models of sub and mother tanks with different cross-sections were established.To solve the problem of calculating heat transfer and evaporation rate for different cross-sections,an equal cross-section optimization design method has been proposed.Established a physical and experi-mental model for unit heat transfer,and researched on the temperature distribution characteristics.By applying numerical simulation and experimental methods,the optimal structural design parame-ters of the sub and mother tanks were obtained.The Research shows the structural design of the sub and mother tanks can be optimized,internal heat transfer can be reduced,daily evaporation rates can be minimized,and the transportation efficiency of supercritical LNG railway tankers can be improved by using the equal section optimization design method.
