摘要
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。
An experimental investigation on the pulse condition of the gas and liquid two-phase flow in the exhaust duct of the 157kW wobble-plate engine has been made. This paper is concerned with the experimental process, the result and the typical spectra, especially the analysis of the exhaust system character of the wobble-plate engine,the influence of cooling water on exhaust,and the relation between exhaust pressure pulse and submerged exhaust noise.
