Description
  • 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.

  • V práci je použita metoda umělé stlačitelnosti k řešení stacionárních a nestacionárních proudění vazké nestlačitelné tekutiny. Metoda je založena na implicitní upwind diskretizaci Navierových-Stokesových rovnic. Rozšíření pro nestacionární simulace je dosaženo buď zvětšením parametru umělé stlačitelnosti nebo použitím duálního času. Model turbulence je SST. Výsledky jsou uvedeny pro nestacionární laminární obtékání kruhového válce a nestacionární turbulentní syntetický proud. (cs)
