摘　　要：本文介绍了某高速巡逻艇主机排气系统布置方案及改进设计。该艇在试验过程中发现主机排气背压超标现象,通过CFD仿真计算和理论估算论证改进方案可行性,经实船验证表明,改进方案的管道阻力与理论估算结果相当吻合。This paper briefly describes the arrangement and improvement of the main engine exhaust system for a high speed patrol vessel.During the test,the exhaust back pressure of the main engine exceeds the standard,and the CFD simulation and theoretical estimation proved the feasibility of the improved scheme.The actual ship verifies that the pipeline resistance of the improved scheme is in good agreement with the theoretical estimation results.

关 键 词：排气系统 排气温度 背压 排气挡板阀
