Continuous boundary condition at the interface for two coupled fluids
Abstract
We consider two laminar incompressible flows coupled by the continuous law at
a fixed interface . We approach the system by one that satisfies a friction Navier
law, and we show that when the friction coefficient goes to infinity, the solutions
converges to a solution of the initial system. We then write a numerical Schwarz-like
coupling algorithm and run 2D-simulations, that yields same convergence result.
