摘　　要：低压排汽缸的气动性能对整个汽轮机组热效率的影响至关重要。采用数值模拟方法,对600MW空冷汽轮机的排汽缸结构进行性能优化,使得排汽缸出口的静压恢复系数较原结构提高了9.2%、总压损失系数降低了5.3%。Low pressure（LP） exhaust hood has a high effect on thermal efficiency of steam turbine. Numerical simulation and aerodynamic optimization on the 600MW air-cooled steam turbine is carried out. The resuhs indicates that the static pressure recovery factor on the exit of exhaust hood increase 9.2%, and total pressure lost factor reduce 5.3%.
