Abstract
Heart failure is a disease, which affects millions of people worldwide. If the disease is to severe, a heart transplantation is the gold standard for treating a terminal heart failure. Unfortunately, a significant shortage of donor organs exist. A tehcnical solution to overcome this problems are Ventricular Assist Devices (VADs). THese VADs are mainly implanted within the body of the patients .
Today, nearly all VADs are designed as turbomachinery, since they have a higher power density as pulsatile pumps, and therefore can be implanted within the human body. Compared to Total Artificial Hearts (TAHs), the VADs do not replace the heart, but assist a weak heart by creating the needed pressure to sufficiently supply the blood flow in the circulatory system.
- Einleitung, warum strömungsmechanische Versuche in VADs wichtig sind
- was wird in dieser Wiki gemacht?
* simulative strömungsmechanische Untersuchungen im turbulenten Strömungsfeld einer axialen VAD * Vergleich zwischen einer hochauflösenden LES als Referenz und einem turbulenzmodellierendem URANS-Verfahren (Standardverfahren in der Industrie bei der Strömungsberechnung in VADs) * Evaluation der fluidmechanischen Parameter (Förderhöhe und Wirkungsgrad) * insbesondere: Vergleich von hämodynamischen Parametern --> äquivalente Spannung und Blutschädigungsparameter * wichtig für Design und Optimierung dieser Systeme
