摘要

本文提出了一种通过在排气管道中注入水雾来降低船用燃气轮机废气温度的方法，目的是降低船舶的红外信号。由于在军舰上进行现场实验测试的困难，计算流体动力学(CFD)技术可以用于预测燃气轮机排气中的相相互作用行为(水雾和废气)。CFD技术试图通过设置和解析数学模型来找到控制相相互作用现象的方程的数值解。

METHODOLOGY APPLIED TO STUDY WATER MIST AS AN INFRARED SIGNATURE SUPPRESSOR IN MARINE GAS TURBINES

This paper proposes a methodology for the reduction of marine gas turbine exhaust gas temperatures via water mist injection into exhaust gas ducts with the aim of reducing a ship’s infrared (IR) signature. Due to the difficulty of conducting live experimental tests on warships, Computational Fluid Dynamic (CFD) techniques can be employed to predict phase interaction behaviour (water mist and exhaust gases) within gas turbine exhausts. CFD techniques attempt to find numerical solutions to the equations that govern phase interaction phenomena through the setting and resolution of mathematical models.
