主燃孔参数对双级轴向旋流燃烧室流动与燃烧特性的影响
Effects of Primary Inlet Hole Parameters on the Flow and Combustion Characteristics of a Two-Stage Axial Swirl Combustor
摘要
Abstract
Simulation was carried out based on the experimental condition of two-stage axial swirl combustor fueled with diesel.The influences of primary hole parameters on flow fields and combustion characteristics of swirl combustor were discussed.The results show that primary recirculation zone area is increased when the distance between the central axis of primary holes and combustor inlet is large,while the change in the diameters of primary holes has a relatively minor effect on the recirculation.The combustion efficiency is obviously reduced to below 90%,when the distance between the central axis of primary holes and combustor inlet is short.But it is slightly influenced by the diameters of primary holes.The outlet temperature distribution fraction is significantly affected by the diameter of the primary hole,with a minimum value of 0.423,while the distance between the central axis of the primary hole and the combustor inlet has little effect on the outlet temperature distribution coefficient,especially on the plane near the combustor outlet.关键词
