1834 2 次元タービン動翼エンドウォール近傍の流れに関する研究 : 流れの可視化と静圧分布特性

抄録

Pressure measurements and surface flow visualization were conducted to obtain a detailed aerodynamic data base on the endwall, suction and pressure surfaces of two-dimensional scale turbine-blade cascade in a low speed wind-tunnel test equipment. The test blade is a typical turbine blade with a low aspect ratio and with a large turning angle. The experiments were conducted at the blade Reynolds number of 4.7×(10)^4 constant and a lamp-black method was applied for the flow visualization. The dominant change of the passage vortex at the endwall and at certain regions of the blade surface is illustrated and pressure distribution characteristics are shown for the blade passage.
