Advanced fan and blading design
Submarine turbine
The blades of this variable-pitch turbine for mine countermeasures were designed with techniques based on vortex theory. The chart is part of the spreadsheet design tool created to predict performance. The prototype performance was very close to predictions.
Melting of product in a shipping container
CFD numerical modelling was used to investigate different methods of melting tallow within a shipping container so that it could be pumped out at its destination.
Advanced fan and blading design
Fundamental momentum theory supported by empirical and experimental techniques is used to design high-performance axial fans. The calculated blade shape parameters were modelled in ProEngineer and rapid prototypes made for design verification. The product is used in low-noise, high-efficiency air conditioners.
Swimming
Goggles
CFD numerical modelling was used to estimate the drag presented by different goggle designs.
Wastewater
treatment
This is an example of a multi-faceted approach to developments in wastewater treatment.
Numerical simulation
Laboratory/Field testing
Pilot plant testing
Analysis
of an exhaust plume
CFD numerical modelling was used to estimate exhaust gas concentration downwind of an engine.
Factory
air pollution
CFD was used to investigate smoke density in a foundry, and to assess measures to improve air quality.
