中文拼音 [liútǐdǎoxiàngyèpiān]
流體導向葉片
英文
flow straightener-
The flow equations are solved using finite difference technique. using body - fitted curvilinear coordinate system treated the boundary conditions. by iteratively solving the flow governing equation and the blade equation, the design of axial flow pump impeller in the quasi - three - dimensional rotational flow can be performed according to the angular momentum distribution, the blade which was designed in the lifting method, flow channel and the blade thickness given
其次在流動無粘性、不可壓及考慮葉片厚度的條件下,依據葉輪內的流動特性,推導了葉輪內三維流動周向平均流動控制方程以及葉片方程;在貼體坐標系中,採用有限差分法求解流動方程和葉片方程;在採用升力法設計出的葉片作為初始葉片、給定葉片速度矩分佈、葉片厚度分佈和葉輪軸面流道幾何形狀條件下,迭代求解流動控制方程及葉片方程,實現了軸流泵葉輪的準三維方法設計。Film cooling of the surface of a gas turbine blade was studied in a large - scale low - speed opening wind tunnel according to actual requirement of the design of aero - engine. the surface of a gas turbine blade was cooled by cylindrical holes in the experiment, with the hole number of fifteen in stator and eight in rotor
應航空發動機設計的要求,在大尺寸低速葉柵傳熱風洞中分別對發動機渦輪導向葉片和動葉表面的氣膜冷卻特性進行了研究,具體研究在不同氣膜孔出流時,在不同主流雷諾數和吹風比情況下葉片表面局部換熱系數的分佈規律。
