Least-Squares Method for Laminar Flow Problems
- 261 Downloads
A least-squares method is used to solve viscous flows encountered in boundary-layers problem. The formulation is described and the minimization equations derived are discretized with a second-order finite difference scheme. The set of algebraic equations is solved by line relaxation. One of the attractive features of the least-squares formulation is that the system behaves well in the presence of separation and reverse flow, as is demonstrated in the case of the boundary-layer flow with adverse pressure gradient.
