Description
  • Tato studie se zabývá numerickým řešením 2D nestacionárního proudění stlačitelné vazké tekutiny ve dvou typech kanálů (nesymetrický a symetrický kanál) pro malé velikosti vstupních rychlostí. Nestacionarita proudu je způsobena periodickým pohybem části stěny kanálu. Numerické řešení je získáno pomocí explicitního MacCormackova schématu s umělou vazkostí Jamesonova typu na strukturované síti tvořené čtyřúhelníkovými buňkami. Problém je formulován pomocí ALE metody. Jsou prezentovány některé numerické výsledky ve zmiňovaných kanálech. (cs)
  • This study deals with the numerical solution of 2D unsteady flows of a compressible viscous fluid in two types of channels (unsymmetric, symmetric) for a low inlet airflow velocity. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall with large amplitudes. The numerical solution is realized by a finite volume method and an explicit predictor-corrector MacCormack scheme with Jameson artificial viscosity using a grid of quadrilateral cells. The moved grid of quadrilateral cells is considered in the form of conservation laws using an Arbitrary Lagrangian-Eulerian method. Numerical results of the unsteady flows in the channels are presented.
