Passive control of wing tip vortices through a grooved-tip design
Junchen Tan, Shūji Ōtomo, Ignazio Maria Viola +1
This paper investigates the characteristics and control of tip vortices generated by a finite wing, focusing on the impact of the novel grooved-tip designs. Tip vortices can lead t…
Unsteady Load Mitigation through Passive Pitch
Yabin Liu, Riccardo Broglia, Anna M. Young +2
Mitigation of load fluctuations due to flow unsteadiness is critical in a broad range of applications, including wind/tidal turbines, and aerial/underwater vehicles. While the use…
Controlling Tip Vortices and Cavitation through Tip Permeability for Tidal Turbines
Yabin Liu, Junchen Tan, Richard H. J. Willden +2
Blade-tip vortices can lead to wakes, cavitation and noise, and their control remains a significant challenge for tidal and wind turbines. In the present work, we propose and inves…
Effect of transverse gust on free-falling plates
Jawahar Sivabharathy Samuthira Pandi, Ahmet Gungor, Chandan Bose +2
The effects of transverse gusts on free-falling plates are investigated using two-way coupled fluid-structure interaction simulations for a Galilei number (Ga) between 10 and 50 an…
Porous plates at incidence
Chandan Bose, Callum Bruce, Ignazio Maria Viola
This paper investigates the effect of permeability on two-dimensional rectangular plates at incidences. The flow topology is investigated for Reynolds number () values between…
Model-scale experiments of passive pitch control for tidal turbines
Stefano Gambuzza, Gabriele Pisetta, Thomas Davey +2
Tidal currents are renewable and predictable energy sources that could prove fundamental to decrease dependency from fossil fuels. Tidal currents, however, are highly unsteady and…
Applying inviscid linear unsteady lifting-line theory to viscous large-amplitude problems
Hugh J. A. Bird, Kiran Ramesh, Shūji Ōtomo +1
Unsteady Lifting-Line Theory (ULLT) is a low order method capable of modeling interacting unsteady and finite wing effects at low computational cost. Most formulations of the metho…
The dispersion of spherical droplets in source-sink flows and their relevance to the COVID-19 pandemic
Cathal Cummins, Olayinka Ajayi, Felicity Mehendale +2
In this paper, we investigate the dynamics of spherical droplets in the presence of a source-sink pair flow field. The dynamics of the droplets is governed by the Maxey-Riley equat…
