Research Interests

My research is on the analysis and design of diffuser augmented wind turbines (DAWTs) using computational fluid dynamics. A DAWT is a wind turbine encased in an aerodynamic shroud, which serves to accelerate incoming airflow before it passes through the blades of the turbine. Accurate modelling of such systems depends heavily on capturing complex interactions between the wake of a wind turbine and the fluid boundary layer of the encasing shroud. High-order methods are preferred for the simulation of such systems to reduce the decay of wake vorticity. As such, overset meshes with structured grids are used frequently in this work. The phenomenon of laminar-turbulent transition has also been shown to greatly influence both the viscous and pressure loads on turbine blades, and accurate transition modelling is another key feature of this project. My research interests include:

  • Wind turbines and wind energy
  • Turbulence and turbulence modelling
  • Laminar-turbulent transition
