Wind Tunnel Facility
At Gradient Wind Engineering, we perform various tests on physical scale models in simulated atmospheric flow conditions generated in our privately owned and operated boundary layer wind tunnel facility in Ottawa, Ontario.
With an overall length of 27 metres and a test section measuring 2.1 metres wide and 1.8 metres tall, our conventional flow-through wind tunnel can accommodate a wide range of physical models. Our wind tunnel is supported by leading-edge instrumentation capable of measuring high-speed mean and fluctuating surface pressures, air velocities, high frequency forces, and pollution concentrations, among other quantities.
We use our facility to investigate a variety of wind flow-related issues, including:
- Wind comfort in pedestrian areas
- Snow drifting, accumulation, and loading estimation
- Cladding pressures on buildings and other structures
- Mean and dynamic wind forces (using the high frequency force balance or high frequency pressure integration techniques)
- Stability of tall and slender wind sensitive structures and sculptures
- Exhaust dispersion from stacks, line and area sources around buildings
- Wind flow over obstacles, drag and lift on aerodynamic or bluff objects
- Unique impacts of wind such as aeolian vibrations (acoustics), among others
