Welcome to WIRE

Mission

The main goal of our research is to improve our understanding and ability to predict turbulent transport of momentum and scalars (e.g., heat, water vapor, pollutants) in environmental flows, with emphasis on the atmospheric boundary layer and wind energy systems. Improved descriptions of those processes are developed and used in engineering, environmental and wind energy applications (e.g., weather, air quality and wind resource assessment models).

Our research involves a synergistic combination of experimental (field and wind tunnel) work, numerical modelling (large-eddy simulation) and theoretical development.

Specific areas of research include:

  • Wind energy
  • Flow over complex terrain
  • Flow in urban canopies
  • Large-Eddy Simulation
  • Thermally stratified flows
  • Boundary-layer turbulence
