Description
  • Tento článek se zabývá numerickou simulací nestlačitelného proudění se stratifikací. Proudění je popsáno Boussinesqovou aproximací Navierových-Stokesových rovnic. Porucha stacionárního řešení je předepisována buď pomocí počáteční podmínky nebo pohybem tělesa v tekutině. Pohyb tělesa je přitom modelován zdrojovým členem v rovnicích. Výsledný systém PDR je potom řešen schématem WENO pátého řádu přesnosti při použití metody umělé stlačitelnosti v duálním čase nebo schématem druhého řádu přesnosti s tlakovou korekcí. (cs)
  • The article deals with the numerical simulation of incompressible flows with stratifications. The flow field is described by the Boussinesq approximation of the Navier-Stokes equations. The disturbance of the steady state with stable stratification is achieved either by the initial condition or by a moving obstacle. This obstacle is modoled via appropriate source terms. The resulting set of PDE is then solved by the fifth order WENO scheme combined with the artificial compressibility method in dual time, or by a second order finite volume scheme combined with the pressure correction.
