Conditions aux limites sur la pression pour les équations de Stokes et de Navier-Stokes. (Boundary conditions on the pressure for the Stokes and the Navier-Stokes equations). (French) Zbl 0613.76028
This note deals with the Stokes problem when the boundary conditions are on the pressure and on its normal derivative. A variational formulation is proposed with an existence result and a discretization scheme based on the finite element method. A generalization of the method to the Navier- Stokes equation is also discussed.
