Flow Separation Prevention on a Turbine Blade in Cascade at Low Reynolds Number - Bok av James P Lake - Häftad
The problem of flow separation from a low pressure turbine blade was investigated. The operating conditions under which the separation occurred were documented through measurement of surface pressure coefficients, boundary layer velocity and turbulence profiles, total pressure loss coefficient and wake velocity momentum deficit. Three different means for reducing the losses associated with the flow separation were also investigated. A boundary layer trip, dimples, and V -grooves were studied as passive..
