Abstract

— Efficient natural conditions on open boundaries for incompressible fiows are derived from a weak formulation of Navier-Stokes équations. Energy estimâtes in velocitypressure are established from a mixed formulation and a ri gourous proof of existence of solutions is given. As an illustration, the conditions are written down for the flow behind an obstacle… (More)
