In this paper, we present an unsplit method for the time-dependent compressible Navier-Stokes equations in two and three dimensions. We use a a conservative, second-order Godunov algorithm. We use a Carte-sian grid, embedded boundary method to resolve complex boundaries. We solve for viscous and conductive terms with a second-order semi-implicit algorithm.(More)
Experiences from using a higher order accurate finite difference multi-block solver to compute the time dependent flow over a cavity is summarized. The work has been carried out as part of a work in a European project called IDIHOM in a collaboration between the Swedish Defense Research Agency (FOI) and University of Linköping (LiU). The higher order code(More)
We present an Embedded Boundary Cartesian Grid method to set Dirichlet, Neumann and extrapola-tion boundary conditions for the compressible Navier-Stokes equations in two-and three dimensions. Of great interest is the coupling LES/wall-model/embedded boundary for simulating compressible flow applications. The main challenge with the embedded boundary method(More)
