We have carried out highly resolved simulations of turbulent open channel flows. The channel wall is covered with different filamentous layers sharing the same thickness ($$h=0.1H$$ h = 0.1 H , where H is the open channel height) and bulk Reynolds nu

We have performed high-fidelity simulations of turbulent open-channel flows over submerged rigid canopies made of cylindrical filaments of fixed length $l=0.25H$ ( $H$ being the domain depth) mounted on the wall with angle of inclination $\theta$ . T

We have performed fully resolved simulations of turbulent flows over various submerged rigid canopies covering the wall of an open channel. All the numerical predictions have been obtained considering the same nominal bulk Reynolds number (i.e. , bei

Copyright © The Author(s) 2020. This paper employs serrated leading edges to inject streamwise vorticity to the downstream boundary layer and wake to manipulate the flow field and noise sources near the blunt trailing edge of an asymmetric aerofoil.

Copyright © The Author(s) 2021. This paper addresses the usefulness of leading edge serrations for reducing aerofoil self-noise over a wide range of angles of attack. Different serration geometries are studied over a range of Reynolds number (Re≈2

Nowadays the majority of civil aircraft employs swept-back wings. This configuration, proposed in the early 30s of last century, has been technologically motivated by the otherwise enhanced drag experienced in transonic cruise condition.

The main focus of this paper is on investigating the noise produced by an aerofoil at high angles of attack over a range of Reynolds number 2x10^5-4x10^5. The objective is not modelling this source of noise but rather understanding the mechanisms of

We have carried out a large-eddy simulation of a turbulent open-channel flow over a marginally dense, fully submerged, rigid canopy. The canopy is made of a set of rigid, slender cylinders normally mounted on a solid wall. The flow in the canopy is r
