基于直接接触凝结理论的汽液两相流升压模型

针对汽液两相流升压装置利用经验模型计算的过程中，仅能对出口压力进行计算，且计算值与实验值有较大误差的弱点，提出了用直接接触凝结（DCC）的理论求解汽液两相流的一维理论模型。计算升压装置的最大出口压力，分析其他参量的变化规律。结果表明，汽液两相流在凝结激波前为泡沫流，在凝结激波后完全凝结成单相水的情况下，升压装置的出口压力达到最大值。

Model of steam-water two-phase flow lifting-pressure mechanism based on direct contact condensation

Since by some empirical models only the discharge pressure could be computed and the errors between experimental and theoretical values would be frequently off-limits,a one-dimensional theoretical model of lifting-pressure mechanism is constructed based on direct contact condensation to compute the maximum pressure and to inspect the variation of other parameters.The result shows two-phase fluid before shock wave is in the state of foam fluid and the exit discharge pressure reaches maximum when two-phase fl...
