Numerical solution and boundary conditions for boundary layer like flows
Abstract
The numerical solution of NavierStokes equations requires a large amount of computer time and storage, particularly for threedimensional high Reynolds number flows. One way of reducing the computer time and storage requirements is to use approximate equations. Consideration is given here to parabolized NavierStokes equations that are derived from the NavierStokes equations by neglecting the diffusion effects in the flow direction (in agreement with boundary layer theory). Solving these equations by marching techniques along the main direction results in considerable savings in both storage and computer time, provided that the solution is acceptable after a single marching sweep.
