Stirring turbulence with turbulence [PDF]
Physics of Fluids, 2015 We stir wind-tunnel turbulence with an active grid that consists of rods with attached vanes. The time-varying angle of these rods is controlled by random numbers. We study the response of turbulence on the statistical properties of these random numbers.

Journal of the Global Power and Propulsion Society, 2018 Diffusers convert kinetic flow energy into a rise in static pressure. This pressure recovery is the primary aerodynamic design objective for exhaust gas diffusers in power-generating steam and gas turbines. The total pressure loss is an equally important

Transitional–turbulent spots and turbulent–turbulent spots in boundary layers [PDF]
Proceedings of the National Academy of Sciences, 2017 Significance Uncovering the constitutive coherent structure in the inner layer of the canonical turbulent boundary layer has remained a central fluid mechanics theme, because it tests our intellectual ability to understand even the simplest external flow.

The fractal turbulent–non-turbulent interface in the atmosphere
Wind Energy Science, 2023 Abstract. With their constant increase in size, wind turbines are reaching unprecedented heights. Therefore, at these heights, they are influenced by wind conditions that have not yet been studied in detail. With increasing height, a transition to laminar conditions becomes more and more likely.
