【摘要】 本文描述了在激波风洞中,来流条件为总压P₀=2.0×10⁵、8.0×10⁵、13.0×10⁵Pa,总温T₀=374.4K,入口马赫数M₁=0.40,进行的平面涡轮叶栅实验。实验内容包括叶片表面压力分布测量,热流率分布测量和激光干涉法显示叶栅通道流场。为了进行比较,文中还给出叶片表面马赫数分布和热流率分布的分析结果。测量值与计算结果规律基本一致。更多还原

【Abstract】 The experiments involving heat transfer, pressure and laser-interferometry visualization for gasturbine plane cascade were performenced in a shock tunnel, free stream conditions: to tal pressure P0 = 2.0×105, 8.0×105, 13.0×105 Pa; total tempreture T0 = 374.4 K ; inlet Mach number M1=0.4. The measuremental distributions of heat flux and pressure on the blades are consistent with calculating results.更多还原
