Flow parameters in diffuser with specific boundary conditions

Original language description

This contribution deals about the flow in difuser with openable walls. There is a separation of a boundary tayer from the walls by larger opening of the diffuser. Same simple adaptations of the wall surface which should eliminate the boundary layer separation elimination were tested. Espacially longitudinal and perperdicular rectangular grooves and wall roughness demonstrated by means of sand paper glued-on on the walls. These aplications could increase a boundary layer turbulization and help with the stabilization of flow on the walls. All alternatives are compared with flow conditions in diffuser with smooth walls. A short part of this contribution deals with PIV measurement and CFD computations.
