Numerical Simulation and Studies of Temperature Rise within a High-pressure Vessel during Refueling
The refueling process of a high-pressure vessel fixed on the rocket-propelled spacecraft was analyzed by the gas kinetics theories and the thermodynamics of variable mass system.A mathematical model was built up to simulate and analyze the refueling process so as to get rules of the pressure and temperature changes and lay the foundation for the design of the fast refueling control algorithm.During the simulation,the thermodynamic model based on natural convection was adopted to make the simulation close to the actual process.The studies shows that the best way to decrease the temperature of the gas within cylinder during refueling and keep the whole time prolong slightly is increase the heat transfer coefficient of cylinder and decrease the volume of stationary tank within measure.
