| Abstract: | The static evaporation rate of LNG container tank for railway application and its intermodal was calculated theoretically.The temperature correction coefficient ktwas introduced to consider the influence of loading LNG medium on the specific heat flow of thermal insulation layer under the temperature range of liquid nitrogen.At the same time,the structure correction coefficient kswas introduced to consider the influence of the structure and the contraction of tank body at low temperature on the heat conduction transfer of the supporting parts.The static evaporation rate was tested experimentally with LNG medium.The theoretical calculation model was verified by the comprehensive test results.On this basis,the influence of relevant key parameters on the static evaporation rate of LNG container tank was analyzed. |
