Start year: 1999

Summary: This project will investigate the dynamics of a rotor suspended by a blood lubricated journal bearing in a rotary blood pump and will make recommendations about the best bearing concept designs. Finding from this project will contribute to the rotary blood pump design undertaken by the research team 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 dynamics of the pump rotor will add greatly to the understanding of the related important factors in blood pump design.
