Solution of the unsteady motion of the body in the liquid flow
Zbavitel, Jan ; Kozák, Jiří (referee) ; Fialová, Simona (advisor)
The thesis deals with CFD solution of flow through mechanical heart valves. The opening part includes a research on the negative impacts of implantation of artificial heart valves and the common approaches used in their modeling. This is followed by a detailed analysis of the dynamic mesh functionality and CFD solution is performed using the open-source library FOAM-extend. Part of the thesis focuses on evaluation of the geometry modifications from the perspective of forming the instabilities of the current and the course of force effects on the valve.
