Prediction of incompressible laminar separated flows using the partially parabolized NavierStokes equations
Abstract
The partiallyparabolized NavierStokes equations are evaluated for steady, twodimensional, laminar, incompressible flows with small, confined regions of recirculation. The equations are solved in primitive variables using finitedifference techniques. The solution procedure involves solving the momentum equations by repeatedly spacemarching in the main flow direction. Typedependent differencing is used to enable downstreammarching even in the reverseflow region. This same computational strategy is also applied to the full NavierStokes equations. External, separated flows as well as the internal, separated flow in a channel with a symmetric, sudden expansion are also considered.
