Centrifugal pumps are some of the most ubiquitous machines in the world, both in industrial as well as homely applications. These machines are limited by the hydrodynamic behaviour of the fluid inside it, as well as its size. When dealing with fluid limitations, flow and pressure are used as a comparison base in order to determine a pump’s service limits. When local pressure drops below vapour pressure, bubbles are formed inside the pump that implode. This phenomenon is known as cavitation, and is one of the challenges when attempting to improve the performance of a pump. Recent developments in biomimetic design have been promising to improve machine performance. This design approach then presents itself as an opportunity to develop tomorrow’s pump, which proposes the next question: Can we improve the performance of a pump by applying biomimetic design to its impeller? This investigation is based upon the idea that the answer is yes. A design that proves to have a higher flow rate while maintaining pressure for a given size would be ideal for space-limited applications. This project was executed through the use of CAD in conjunction with photographs and measurements taken by previous researchers, together to do CFD simulations. A sailfish inspired impeller was compared with a traditional one. An efficiency increase of 3.5% and 0.2% at overspeed and nominal conditions was measured. Discharge head saw an increase of 5% and 8% at nominal and overspeed conditions respectively. This shows a promising prospect for performance improvements over current designs. Further research is advised in order to validate the findings of this investigation.
