Flow Solvers and Validation

摘要: Up to this point, we have reviewed numerical algorithms for computing viscous incompressible flows, primarily using primitive variables along with finite difference and volume frameworks. The solution methods flows are based on the assumption that flow can be approximated by Navier–Stokes equations. Once a algorithm is developed, solvers software procedures need developed compute fluid dynamic problems. This process includes setting up problem, solving proper initial boundary conditions, then post-processing computed results. These solutions include several levels of approximations including algorithmic, geometry-related physical-modeling related approximations.
