Performance quantification of tidal turbines subjected to dynamic loading

open access: yes, 2013
The behaviour of Tidal Stream Turbines (TST) in the dynamic flow field caused by waves and rotor misalignment to the incoming flow (yaw) is currently poorly understood.

Wave-current interaction in strongly sheared mean flows

open access: yes, 2016
Kirby, James T.Existing theories of wave-current interaction mostly assume that waves propagate on currents which vary weakly in the vertical direction. In most cases, the assumption is satisfied.

A study of sheared turbulence/shock interaction: velocity fluctuations and enstrophy behaviour [PDF]

open access: yes, 2012
Direct Numerical Simulations of the idealized interaction of a normal shock wave with several turbulent shear flows are conducted. We analyse the behaviours of velocity and vorticity fluctuations and compare them to what happens in the isotropic ...

Controlled Engineering of 2D Alkali‐Iron‐Chloride Compounds and Lateral Quantum Heterostructures Within Confined Graphene Nanoreactors

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a programmable atomic engineering strategy for 2D materials using Å‐scale nanoreactors formed by bilayer graphene (BLG) intercalation. A new class of alkali‐iron‐chloride compounds, along with lateral heterostructures composed of monolayer alkali halides and iron chlorides, is revealed.
