| Abstract: In the talk we discuss a variational multiscale approach for the pressure subgrid modeling in the Galerkin method for incompressible Navier-Stokes equations. We relate the approach with a stabilization procedure of least-square type known as grad-div stabilization and consider the search of optimal stabilization parameters as a trade-off between mass and energy balance in the discrete system. Application to numerical simulation of laminar and turbulent flows is studied |
