Description
  • The article deals with the numerical simulation of incompressible flows with stratifications. The mathematical model is based on the Boussinesq approximation of the Navier-Stokes equations. The flow field in the towing tank with a moving cylinder is modeled for wide range of Richardson numbers. This obstacle is modeled via appropriate source terms. The resulting set of PDE is then solved by the fifth order WENO scheme, or by a second order finite volume AUSM MUSCL scheme. Both schemes are combined with the artificial compressibility method in dual time.

  • Článek se zabývá numerickou simulací nestacionárního nestlačitelného stratifikovaného proudění. Matematický model je založen na Boussinesquově aproximaci Navierových-Stokesových rovnic. Bylo řešeno proudění ve vlečném tanku s válcovým tělesem pro široký rozsah Richardsonových čísel. Těleso je modelováno pomocí zdrojového členu. Pro numerické řešení je užito buď WENO schéma pátého řádu nebo AUSM MSCL metoda konečných objemů druhého řádu. Obě metody jsou kombinovány s metodou umělé stlačitelnosti v duálním čase. (cs)
