Analysis of Laminar and Turbulent Symmetric Blunt Trailing-Edge Flows.

Contributions are made to interacting viscous flow theory for symmetric separated flow past blunt airfoil trailing edges. A theoretical and computational technique for predicting turbulent, high Reynolds number, separation and near wake flow is provided. A detailed assessment of a viscous/inviscid iteration and an inverse boundary layer solution procedure is provided through a systematic series of test examples. These involve subsonic laminar and turbulent flows past flat plate and thickened flat plate (blunt trailing-edged) airfoils. In addition, a general approach is outlined for incorporating local strong interaction solutions into an overall viscous solution procedure for isolated airfoils and cascades. (Author)
