马赫数对不同负荷分布形式的高负荷低压涡轮性能的影响
Effect of Mach Number on High Loaded Low Pressure Turbine with Different Loading Distribution
摘要
Abstract
This paper numerically simulated the flow filed of high loaded low pressure turbine with three xind of loading distribution at wind range Mach number. Through analysis we can conclude that:the aft loaded airfoil is more sensitive to Mach number compared to front and mid loaded airfoil,and the aerodynamic loss is very obvious for aft loaded airfoil at the range of high Mach number with is larger than front and mid loaded airfoils. The aerodynamic loss of aft loaded airfoil increased by 100%compared to mid loaded airfol when the export isentropic Mach number is 1.关键词
