In this work, artificial compressibility method is used to solve steady and unsteady flows of viscous incompressible fluid. The method is based on implicit higher‐order upwind discretization of Navier–Stokes equations. The extension for unsteady simulation is considered by increasing artificial compressibility parameter or by using dual time stepping. Turbulence models are eddy‐viscosity SST model and explicit algebraic Reynolds stress model. Results for steady turbulent flow over confined backward‐facing step, unsteady laminar flow around circular cylinder and for unsteady turbulent free synthetic jet are presented.
