Research on Pneumatic Performance of Aero-Engine Blades through Function Method

Abstract:

When we research on pneumatic performance of aero-engine blades,some functions are not solved directly in physical domain because blade coordinates are unknown,but they can be solved after being transformed to computational domain.For potential function and stream function have the orthogonality themselves,mesh of computational domain is orthogonal after orthogonal transformation and the functions are solved easily.The existence conditions are two-dimensional flow continuity equations.If fluid is irrotational and powerful flow,potential function and stream function are both usesd to describe flow field’s velocity,pressure distribution.etc.Therefore,we select potential function and stream function as basic method for researching optimization design of aero-engine blades.
