摘　　要：基于双流体模型的理论稳态综合水力学模型编制了模拟程序,发现持液率的微小波动将导致求解的压力、流速等结果严重偏离准确值。为避免持液率对求解结果的影响,提出了一种简化的计算模型,并将该模型计算结果与试验数据进行了对比,结果表明,模拟结果与试验数据有很好的吻合。A simulation program based on steady synthetic hydraulics model on theory of two-fluid model isprogrammed and the subtle change of liquid holdup is found,which will make the pressure and velocity badly deviate from accurate value.In order to turn away the influence of the liquid holdup,authors put forward a simplified model and the calculated results from the model are compared with experimental data.Comparison results show that the simulated results are highly agreeing with the experimental data.
