Abstract
Centrifugal pumps are the most common type of pump used in industrial, agricultural and domestic fields. To design a higher-performance pump, design optimization using mechanical concepts is required. This project covers the study of the poorly understood mechanical behaviour, performance and internal flow behaviour at higher rotational speeds of the XVIVO cirQlife pump – a centrifugal pump used in the field of biomedical engineering for a hypothermic- and normothermic machine perfusion medical device. The characteristics of the pump have been investigated through a combination of numerical analysis of the linear dynamics and nonlinear fluid dynamics, and experimental tests on the pump performance. Furthermore, the influence on the performance and the internal flow behaviour by the holes in the shaft of the impeller has been investigated by altering the design both experimentally and numerically. Finally, conclusions have been made based on the results and discussion of the experimental and numerical models and recommendations have been given for future research to investigate possible design changes to the centrifugal pump.
