Solution of the thin-layer Navier-Stokes equations for laminar transonic flow
Abstract
A finite-volume-based numerical method for the solution of the thin-layer Navier-Stokes equations is presented. The convective part of the fluxes is solved using a flux-vector splitting method and the diffusive part is solved using central differences. The equations are integrated in time with an approximately factored bidiagonal scheme. Convergence is accelerated by applying a multigrid technique. Results are presented for laminar transonic flows over a NACA 0012 airfoil.
