NSIKE - An Incompressible Navier-Stokes Solver for Unstructured Meshes

Abstract : A new solver for 3D incompressible Navier-Stokes equations is developed. The standard k-epsilon turbulence model is implemented for turbulent flow simulation. The incompressible Navier-Stokes solver is based on Chorin's projection method. with finite element discretization. The computation of intermediate velocity and turbulence variables is done explicitely and the stabilization of convection terms is based on PSI (positive streamwise invariant) residual distribution scheme. The Poisson problem for pressure is solved using conjugate gradient technique. In the case of turbulent flow simulations the wall-laws are used for solid boundaries. Test cases presented are 2D flat plate, cavity, backward facing step, circular cylinder and 3D cavity, backward facing step, both in laminar and turbulent regime.
