摘要
采用κ-ε两方程模型和壁面函数法数值模拟舰船排气系统红外抑制装置缩比模型的湍流场和温度场分布.经实验校模后利用自模化原理将数值模拟方法推广到实物装置上去.在建立了观察点与装置有关区域之间看视关系后,利用Hotel的区域法就可计算获得装置的红外辐射场分布.
The κ ε two equation model and wall function were adopted to numerically simulate the turbulent flow and temperature field of the infrared suppression device of marine exhaust system. After experimental tests, the self simulation principle was used to develop the numerical simulation method to physical device. The Hottel method was used to calculate the distribution of infrared radiation after the view factor between viewpoint and device was established.
