    Wall Pressure Signature in Compressible Turbulent Boundary Layers

    Large-scale turbulent flow structures associated with positive and negative wall pressure fluctuations in a compressible turbulent boundary layer are investigated. Experiments are conducted in a closed-loop tr...

    Vortex Dynamics in Nonuniform Compressible Flow

    The convection of vortices in convergent nozzles and Laval nozzles is investigated experimentally and numerically. All studies are done for the plane case. The experiments are performed in a transonic wind tun...

    Wave Models for Unsteady Separation and Jets

    The unsteady behaviour of separation and jets is explained in terms of the propagation and amplification of waves. The formation of waves on the boundaries of separation and jets is often caused by an instabil...
