Research on Mechanism of Two Phase flow Lifting Pressure Equipment and Output Regulation

  Taking into account the process and mechanism of lifting pressure were complex due to the condensation and shock wave,a one-dimensional theory model based on direct contact condensation is presented to analyze the lifting pressure character of steam-water two phase flow injector,and some key issues,such as inter-phase mass transfer computed by the average condensation heat transfer coefficient and phase volume fraction determined by steam plume,are discussed in detail.The regulations of discharge mass flow and output temperature are decoupling control according to the theory model,and the inlet water mass flow is to determine the output temperature,the variable throat section of steam nozzle is to determine the discharge mass flow.
