Thermal Cycling Toughness and Strength Estimation of Cryogenic Filled Tank

At present, technologies based on liquid natural gas (LNG) using start to find a wide use. They also demand technologies of working fluid storage and transportation in cryogenic liquid condition. The working fluid will be used after its regasification from cryogenic liquid condition. When the gas cylinder is filled with gas, there is a danger of exceeding the temperature stresses in the cylinder walls. For the study, there is a method for calculating unsteady thermal conductivity for studying the temperature stresses in the wall of a gas cylinder during its interaction with an evaporating cryogen. This method is used for determining the thermoelastic stresses of the cryogenic filled tank. The CAE- calculation of the strength of the cryogenic filled tank is also done
