Abstract: Side exhaust system is an exhaust system configuration which is suitable for small ships that cannot install exhaust pipe due to the limited space arrangement. It can be characterized of the high flexibility, aesthetics and stealthiness. There are many factors involved in the design of this exhaust system. The current study carries out the simulation of this exhaust system from the arrangement and back pressure of exhaust pipes, and provides suggestions for the preliminary design. This article simulated the back pressure and arrangement for the design, and provided some advice of the preliminary design.

Key words: side exhaust, pipe arrangement, exhaust back pressure, appendage

摘要： 舷侧排气是一种适应于小型船舶,且由于甲板上空间布置紧张而无法安装排气管情况下使用的排气系统布局。具有较高的灵活性、美观性和隐蔽性。该排气方式的设计涉及许多方面因素。文章从排气管的布置以及背压方面,对该排气方式进行模拟,并对初步设计提出了建议。
