An implicit multiblock coupling for the incompressible Navier-Stokes equations

摘要

In the present work, we describe an interface treatment of multiblock computation for the incompressible Navier-Stokes equations discretized upon a finite volume marker and cell (MAC) approach. The connection between the different blocks is based on velocity interpolation only. The originality of this work is that the polynomial interpolation coefficients are present in the final linear system and ensure that the equations are globally resolved.
