| 1 | THE NAVIER-STOKES EQUATIONS WITH THE KINEMATIC AND VORTICITY BOUNDARY CONDITIONS ON NON-FLAT BOUNDARIES显示文摘We study the initial-boundary value problem of the Navier-Stokes equations for incompressible fluids in a general domain in Rn with compact and smooth boundary,subject to the kinematic and vorticity boundary conditions on the non-flat boundary. We observe that,under the nonhomogeneous boundary conditions,the pressure p can be still recovered by solving the Neumann problem for the Poisson equation. Then we establish the well-posedness of the unsteady Stokes equations and employ the solution to reduce our initial-boundary value problem into an initial-boundary value problem with absolute boundary conditions. Based on this,we first establish the well-posedness for an appropriate local linearized problem with the absolute boundary conditions and the initial condition (without the incompressibility condition),which establishes a velocity mapping. Then we develop apriori estimates for the velocity mapping,especially involving the Sobolev norm for the time-derivative of the mapping to deal with the complicated boundary conditions,which leads to the existence of the fixed point of the mapping and the existence of solutions to our initial-boundary value problem. Finally,we establish that,when the viscosity coefficient tends zero,the strong solutions of the initial-boundary value problem in Rn(n ≥ 3) with nonhomogeneous vorticity boundary condition converge in L2 to the corresponding Euler equations satisfying the kinematic condition. | Dan Osborne | 2009 | Acta Mathematica Scientia2009，29，4： | 1 |
