Allan Wallace specializes in fluid mechanics and often uses a combination of experimental work, theoretical analysis and numerical modeling. Avocet is a licensee of the Phoenics CFD code.
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.
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.
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.
CFD numerical modelling was used to estimate the drag presented by different goggle designs.
This is an example of a multi-faceted approach to developments in wastewater treatment.
Pilot plant testing
CFD numerical modelling was used to estimate exhaust gas concentration downwind of an engine.
CFD was used to investigate smoke density in a foundry, and to assess measures to improve air quality.
