Start year: 2003

Summary: This project will investigate, both numerically and experimentally, the stability of the impeller-bearing system of a rotary blood pump and will make recommendations about the optimum bearing configurations. Findings from this project will contribute to the commercialisation of the blood pump undertaken by the research Group formed by the staff from UTS, UNSW and VentrAssist Pty Ltd - the first of its kind in Australia. Rotary blood pumps are at the leading edge of cardiac assist technology worldwide and an investigation of the impeller dynamics will add greatly to the understanding of the related important factors in blood pump design.
