Prediction of laminar separated flows using the partially parabolized NavierStokes equations
Abstract
The partially parabolized NavierStokes equations are evaluated for steady, twodimensional, laminar, incompressible flows with small, confined regions of recirculation. The steadyflow equations are solved in primitive variables using finitedifference techniques. Typedependent differencing is used to permit downstreammarching even in the reverseflow region. Consideration is given to external separated flows as well as the internal separated flow in a channel caused by a symmetric, sudden expansion. Comparisons are made with results obtained using the full NavierStokes equations and with experimental measurements. For the external flows, results obtained using the fully parabolic inverse boundarylayer procedure are also presented and compared.
