Self-excited oscillation of the thin-walled elastic tubes
 Chlup, Hynek ; Maršík, František ; Konvičková, S.
The simulation of the fluid flow through elastic pipes has many applications in a blood flow through human vessels – investigation of such phenomena as an atherosclerosis generation in artery walls, the Korotkoff's sounds generation or modeling of vascular mechanical substitutes (the so called "stents") and is therefore widely studied. Aim task is to solve the blood flow through the elastic tubes analytically, numerically and experimentally and to analyze the relation of the mechanical properties of the blood and of the vessel wall and flow instabilities, all focused on biomechanics of the cardio-vascular system. The analysis shows that frequency of self-excited oscillations increases with the decrease of arterial compliance.

Experimentální linky pro samobuzené kmitání elastických trubic
 Chlup, Hynek ; Maršík, František ; Konvičková, S.
Aim task is to solve the blood flow through the elastic tubes analytically, numerically and experimentally and to analyze the context of the mechanical properties of the blood (viscosity) and of the vessel wall (elastic modules) with their instability (Korotkoff’s sounds), all with the proper intention to biomechanics of the cardio-vascular system.
