Multi-physics modelling of bearingless pumps

The transition towards electrified and energy-efficient industrial systems demands new technologies capable of operating at high speed with improved efficiency, reliability, and reduced maintenance. 

Bearingless pumps represent a promising technology because they eliminate conventional mechanical bearings and shaft seals, thereby reducing frictional losses, wear, and maintenance requirements while enabling fully electrified actuation and control.

Research has demonstrated the feasibility of bearingless pumping systems but needs better understanding of their multiphysics interaction.

This PhD project will develop advanced physics-based modelling approaches for bearingless pumps, focusing on the strongly coupled interactions between internal fluid flow, electromagnetic suspension forces, and rotor dynamics. 

The project will investigate stability limits, force generation mechanisms, efficiency losses and thermal interactions to establish improved design methodologies for future industrial applications.

You will join a multidisciplinary research environment at The University of Queensland with expertise in:

• Fluid-structure interaction
• Nonlinear dynamics and stability
• Rotating machinery
• Multi-physics modelling
• Computational fluid dynamics
• Energy-efficient industrial systems

The project is embedded within an international collaboration with the Technical University of Denmark (DTU) and industrial partner Danfoss, ensuring opportunities for international research engagement, access to industrial data, and participation in collaborative research activities.

A parallel PhD position is also being advertised at DTU, and the two PhD candidates will collaborate closely under a joint DTU-UQ supervision framework, with opportunities for research exchange and interaction between the two. 

This project is supported by the Research project scholarship.
