摘要
在两种典型船用燃气轮机排气系统红外抑制装置数值计算和试验测量的基础上 ,根据相似理论 ,分析讨论了模化比对气流和壁面温度场分布以及红外辐射强度的影响 .根据实物排气红外抑制系统的相应参数和模化比影响的量级 。
Based on the results of calculation and measurement of the two kinds of marine gas turbine exhaust systems with the infrared signature suppression devices, according to the similarity theory, the effects of scale factor on the temperature profile (of air-flow and tube wall), and infrared radiant intensity(of exhaust plumes and exhaust uptake inner wall) of the exhaust system were analyzed and discussed. Based on the corresponding parameters of real ship exhaust systems as well as the magnitude of scale factor impacts, the recommended values for selecting the scale factor were estimated and presented.
