Preliminary computational study of turbulent flow in the boundary layer of the suction side of an inclined plate

A turbulent flow behind a simple thin planar air foil with rounded edges at moderate angle of attack is studied. Reynolds number is about 65 000. First results of CFD analysis are presented, which will be validated with PIV measurements made by Institute of Thermomechanics of the Czech academy of Sciences. All the work is carried out to support the "New theory of flight" presented by Hoffman and Johnson [1]. Large eddy simulation is employed to verify the existence of streamwise vorticial structures and their description. The 3D transient simulation provides more information than the data from a set of PIV measurement planes and it offers also finer time resolution.
