HULL TEMPERATURE PREDICTION METHOD FOR CRYOGENIC FLUID LEAKAGE USING SPREADING MODEL

摘要

PURPOSE: A hull temperature prediction method in cryogenic fluid leakage by using a dispersion model is provided to calculate physically valid value in cryogenic fluid leak and to predict the temperature change of hull. CONSTITUTION: If cryogenic fluid is leaked, a fluid film is leaked through a barrier structure. A thermal exchange balance condition is calculated between gas and a steel plate. The growth rate of the fluid film is calculated by balance between the cryogenic fluid and the vaporized cryogenic fluid by passing through a glass wool. The gas is vaporized from the fluid film. A hull temperature function of a ship is drawn.
