The artificial compressibility method is used to solve steady and unsteady flows of viscous incompressible fluid. The method is based on the implicit higher order upwind discretization of the Navier-Stokes equations. The extension for unsteady simulation is considered by increasing artificial compressibility parameter or by using dual time stepping. Both methods are tested on laminar flow around the circular cylinder and used to simulate unsteady turbulent flows by URANS approach. The simulated cases are the synthetic jet flow in a branched channel.
