R. Jason Hearst
Om
N.B.: I will be on sabbatical for the 2024-2025 academic year and unfortunately will not be taking masters or internship students at NTNU in this period.
Research
My research is focussed on the experimental measurement of turbulent flows. Some topics that I am actively pursuing are:
- The generation of bespoke turbulence at high Reynolds numbers.
- The interaction of turbulence at a gas-liquid (air-sea) interface.
- The impact of turbulence on various geometries (e.g., airfoils, buildings, wind turbines).
- The influence of free-stream turbulence on a turbulent boundary layer.
Visit my group's webpage for more details.
