Flow Separation Prevention On A Turbine Blade In Cascade At Low Reynolds Number, James P. Lake
Flow Separation Prevention On A Turbine Blade In Cascade At Low Reynolds Number, James P. Lake
Theses and Dissertations
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 means requiring no additional energy to reduce the separation losses. The boundary layer trip was only successful for an inlet and axial chord Reynolds number of 50k with a reduction …
Wind Tunnel Investigation Of Joined Wing Configurations, Jennifer Corneille
Wind Tunnel Investigation Of Joined Wing Configurations, Jennifer Corneille
Theses and Dissertations
The Air Force Research Laboratory's Munitions Directorate is looking to extend the range of its small smart bomb. One proposed idea is to retrofit the bombs with a wing kit, particularly a joined wing configuration. A typical joined wing configuration is one where the wings are positioned in such a way that they form a diamond in both plan and front views. The purpose of this study is to conduct low speed wind tunnel testing of the joined wing configuration to help determine if the joined wing is more beneficial than a single wing configuration. Configurations with differing sweep angles …
