Published in 2018 at "Flow, Turbulence and Combustion"

DOI: 10.1007/s10494-018-9914-6

Abstract: Self-activated feathers are used by almost all birds to adapt their wing characteristics to delay stall or to moderate its adverse effects (e.g., during landing or sudden increase in angle of attack due to gusts).… read more here.

Published in 2017 at "Energy"

DOI: 10.1016/j.energy.2017.03.071

Abstract: In this paper, we investigated the effect of profile modifications on straight bladed VAWTs equipped with symmetrical aerofoil (NACA 4-digit series of NACA 0012, NACA 0015, NACA 0018, and NACA 0021). Aerofoil profile modifications being… read more here.

Published in 2020 at "Journal of Sound and Vibration"

DOI: 10.1016/j.jsv.2020.115574

Abstract: Abstract This paper is predominantly an experimental study into the reduction of turbulence - aerofoil interaction noise by the introduction of aerofoil porosity. In this paper we study three scenarios applied to flat plates: (a)… read more here.

Published in 2020 at "Journal of Fluid Mechanics"

DOI: 10.1017/jfm.2020.467

Abstract: Abstract The suction force at the leading edge of a round-nosed aerofoil is an important indicator of the state of the flow over the leading edge and, often, the entire aerofoil. The leading-edge suction parameter… read more here.

Published in 2021 at "Journal of Fluid Mechanics"

DOI: 10.1017/jfm.2021.452

Abstract: This paper presents an experimental investigation of the characteristics of laminar– turbulent transition occurring on a flat-plate boundary layer due to the interaction with a non-impinging aerofoil wake. Previous studies have tended to focus on… read more here.

Published in 2020 at "Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering"

DOI: 10.1177/0954410018795542

Abstract: The effect of plasma actuators on shock wave–laminar boundary layer interaction was studied experimentally on transonic laminar aerofoil. The unsteady characteristics of the separation zone including the transonic buffet were measured. Two kinds of electrical… read more here.
