摘要

旋流分离器产生的内外双层旋流具有稳定火焰以及冷却壁面的潜能,为此文中应用雷诺应力模型(RSM)对某种结构的旋流冷壁燃烧室的流动特性进行了数值仿真。结果表明:旋流冷壁燃烧室能够实现内外双层旋流流动,具有较好的壁面冷却效果。冷热态条件下,总压损失系数为0.9%和1%,表现出低阻特性;内外旋流分界面平均约占半径的70%。燃烧区域分界随燃料喷入速度的增大而增大,燃料喷射速度为12m/s时,燃烧区域最大,平均约占半径的56%。

Abstract

Inner and outer swirl produced by cyclone separator have the potential of stabilizing flame and cooling wall, therefore, in this paper, RSM model was used to simulate flow characteristics of a swirl-cooled combustion chamber. The results show that swirl-cooled combustion chamber can achieve inner and outer swirl flow, and has good cooling effect of the wall. Under cold and hot conditions, the total pressure loss coefficient is 0.9% and 1%, showing low resistance characteristics of the structure, the average boundary of inner and outer swirl is 70% of the swirl radius. The boundary of combustion increases with the increase of fuel injection rate. The combustion zone is biggest when fuel injection rate is 12 m/s, the average is 56% of the radius.
