对１５７ｋｗ摆盘式发动机排气管内气液两相流脉动状态进行了实验研究分析。文中概述了实验过程，对试验结果、典型图谱作了分析，着重分析了摆盘机排气系统的特点和冷却水对排气的影响，并进一步分析了排气压力脉动与水下排气噪声的关系。
The pulsating state of gas-liquid two-phase flow in 157kw wobble plate engine exhaust pipe was studied experimentally. In this paper, the experimental process is summarized, the test results and typical maps are analyzed. The characteristics of the exhaust system and the influence of cooling water on the exhaust gas are analyzed emphatically. The relationship between exhaust pressure pulsation and underwater exhaust noise Relationship.
