Abstract: Abstract In this work, an artificial compressibility method is used to solve steady and unsteady flows of viscous incompressible fluid. The method is based on implicit higher order upwind discretisation of Navier-Stokes equations. The extension for unsteady simulation is considered by increasing artificial compressibility parameter or by using dual time stepping. Turbulence is modelled by the eddy-viscosity SST (Shear Stress Transport) model. Results for unsteady laminar flows around a circular cylinder and for unsteady turbulent free synthetic jet are presented.
