提出一种气液两相喷管的设计方法。该方法基于简化的气液两相喷管物理模型及给定的气液两相质量流率和期望压力分布，通过求解流动方程，从而得到满足条件的实际喷管线型。然后对所设计喷管内的流动参数进行分析，进一步证实所设计喷管的正确性。本文提出的设计方法解决了气液两相喷管设计困难的问题，具有较大的工程应用价值。

A design method for gas-liquid two-phase nozzle is proposed in the paper. The method is based on simplified physical model,given two-phase mass flow rate and expected pressure distribution. The actual nozzle configuration can be obtained by sloving flow equations. Then,flow parameters in the nozzle are analysed according to designed nozzle. It is confirmed that the designed nozzle is reasonable. The method proposed can overcome the difficulty in design of gas-liquid two-phase nozzle and is of great engineering value.
