Efficient Transient Numerical Method for the Phase Change Process in Cryogenic Tanks
Simulating the self-pressurization process in closed cryogenic tanks usually consumes tremendous computational resource.It is too long to simulate the long-term transient physics hap-pened in the tanks with normal commercial computational fluid dynamics software.This study proposes an efficient solver to simulate the self-pressurization process induced by the liquid-vapor phase change in the cryogenic tanks based on the open source platform OpenFOAM.Ten times improvement in the calculation speed is achieved compared to the widely-used commercial solver Fluent®.The values of the models coefficients are also discussed to reduce the simulation's error.The comparison between the results from the present results and early thermodynamic node models indicates that the accuracy of the present model is significantly improved.
