Description
  • The article deals with the numerical simulation of unstable, 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. The 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 proudění se stratifikací. Matematický model je založen na Boussinesqově aproximaci Navierových-Stokesových rovnic. Proudové pole ve vlečném tanku s pohybujícím se válcem je modelováno pro široký rozsah Richardsonových čísel. Těleso je modelováno jako přídavný zdrojový člen. Výsledný systém PDR je řešen buď WENO schématem pátého řádu nebo AUSM MUSCL schématem druhého řádu. Obě schémata jsou kombinována s metodou umělé stlačitelnosti v duálním čase. (cs)
