Stable Robin boundary conditions for the Navier-Stokes equations
2011 (English)Report (Other academic)
In this paper we prove stability of Robin solid wall boundary conditions for the compressible Navier-Stokes equations. Applications include the no-slip boundary conditions with prescribed temperature or temperature gradient and the rst order slip-ow boundary conditions. The formulation is uni-form and the transitions between dierent boundary conditions are done by a change of parameters. We give dierent sharp energy estimates depending on the choice of parameters.
The discretization is done using nite dierences on Summation-By-Parts form with weak boundary conditions using the Simultaneous Approximation Term. We verify convergence by the method of manufactured solutions and show computations of ows ranging from no-slip to substantial slip.
