Abstract: Based on the analysis on steam accumulator charge system with theories of variable mass system thermodynamics and viscous fluid mechanics, mathematic models of each system component were built up. Then the steam charging process was simulated by system simulation model based on Simulink of Matlab, and the obtained results of dynamic characteristics provide the optional method and parameters for design of system.
Key words: steam accumulator; variablemass; control valve; modeling; simulation
