Applications of a moving surface drag model: From Stokes waves to offshore wind farms
Manuel Ayala, Zein Sadek, Raul. B Cal +2
Offshore wind farms operate within the marine atmospheric boundary layer, where ocean waves can modify air-sea momentum transfer, turbine inflow, and wake recovery. Wave-resolved s…
Stable Boundary Layers with Subsidence: Scaling and Similarity of the Truly Steady State
Thijs Bon, Raúl Bayoán Cal, Johan Meyers
The stable boundary layer (SBL) subjected to large-scale subsidence is studied through large-eddy simulations (LESs) with fixed surface temperature and a linear subsidence velocity…
Lagrangian modeling of a non-homogeneous turbulent shear flow: Molding homogeneous and isotropic trajectories into a jet
Bianca Viggiano, Thomas Basset, Mickaël Bourgoin +4
Turbulence is prevalent in nature and industry, from large-scale wave dynamics to small-scale combustion nozzle sprays. In addition to the multi-scale nonlinear complexity and both…
Coriolis force deflects wind plant wakes left in the Northern Hemisphere
Natalie Violetta Frank, Maria Eletta Negretti, Joel Sommeria +2
The physical growth of wind energy over several decades, caused a re-investigation mesoscale effects on wind plant dynamics. At a large scale operation, understanding the interacti…
Effects of wavelength on vortex structure and turbulence kinetic energy transfer of flow over undulated cylinders
Kathleen Lyons, Raúl Bayoán Cal, Jennifer A. Franck
Passive flow control research is commonly utilized to provide desirable drag and oscillating lift reduction across a range of engineering applications. This research explores the s…
Entrainment, diffusion and effective compressibility in a self-similar turbulent jet
Thomas Basset, Bianca Viggiano, Thomas Barois +5
An experimental Lagrangian study based on particle tracking velocimetry has been completed in an incompressible turbulent round water jet freely spreading into water. The jet is se…
Single inertial particle statistics in turbulent flows from Lagrangian velocity models
J. Friedrich, B. Viggiano, M. Bourgoin +2
We present the extension of a modeling technique for Lagrangian tracer particles [B. Viggiano et al., J. Fluid Mech.(2020), vol. 900, A27] which accounts for the effects of particl…
Lagrangian diffusion properties of a free shear turbulent jet
Bianca Viggiano, Thomas Basset, Stephen Solovitz +7
A Lagrangian experimental study of an axisymmetric turbulent water jet is performed to investigate the highly anisotropic and inhomogeneous flow field. The measurements were conduc…
Dynamic stall of an airfoil under tailored three-dimensional inflow conditions
Dominik Traphan, Tom T. B. Wester, Matthew Melius +3
Rotor blades of wind turbines in the atmospheric boundary layer regularly experience the aerodynamic phenomenon of dynamic stall consisting of a temporary overshoot of lift and det…
Modelling Lagrangian velocity and acceleration in turbulent flows as infinitely differentiable stochastic processes
Bianca Viggiano, Jan Friedrich, Romain Volk +3
We develop a stochastic model for Lagrangian velocity as it is observed in experimental and numerical fully developed turbulent flows. We define it as the unique statistically stat…
On the decay of dispersive motions in the outer region of rough-wall boundary layers
Johan Meyers, Bharathram Ganapathisubramani, Raúl Bayoán Cal
In rough-wall boundary layers, wall-parallel non-homogeneous mean-flow solutions exist that lead to so-called dispersive velocity components and dispersive stresses. They play a si…
Turbulent Boundary Layer Features via Lagrangian Coherent Structures, Proper Orthogonal Decomposition and Dynamic Mode Decomposition
Naseem Ali, Murat Tutkun, Raúl Bayoán Cal
High-speed stereo PIV-measurements have been performed in a turbulent boundary layer at Re of 9800 in order to elucidate the coherent structures. Snapshot proper orthogonal dec…
