Optimal first-order error estimates of a fully segregated scheme for the Navier-Stokes equations
A first-order linear fully discrete scheme is studied for the incompressible time-dependent Navier–Stokes equations in three-dimensional domains. This scheme is based on an incremental pressure projection method and decouples each component of the velocity and the pressure, solving in each time step...

| description |
A first-order linear fully discrete scheme is studied for the incompressible time-dependent Navier–Stokes equations in three-dimensional domains. This scheme is based on an incremental pressure projection method and decouples each component of the velocity and the pressure, solving in each time step, a linear convection–diffusion problem for each component of the velocity and a Poisson–Neumann problem for the pressure. Using an inf–sup stable and continuous finite-elements approach of order 0 (h) in space, unconditional optimal error estimates of order 0 (k + h) are deduced for velocity and pressure (without imposing constraints on the mesh size h and the time step k). Finally, some numerical results are performed to validate the theoretical analysis, and also to compare the studied scheme with other current first-order segregated schemes. |
