Vapour phase growth and grain boundary structure of molybdenum disulphide atomic layers. [PDF]

open access: yesNature Materials, 2013
Single-layered molybdenum disulphide with a direct bandgap is a promising two-dimensional material that goes beyond graphene for the next generation of nanoelectronics. Here, we report the controlled vapour phase synthesis of molybdenum disulphide atomic

Acoustic boundary layers as boundary conditions [PDF]

open access: yesJournal of Computational Physics, 2018
The linearized, compressible Navier-Stokes equations can be used to model acoustic wave propagation in the presence of viscous and thermal boundary layers.

A nonstandard fitted operator finite difference method for two-parameter singularly perturbed time-delay parabolic problems

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
In this article, a class of singularly perturbed time-delay two-parameter second-order parabolic problems are considered. The presence of the two small parameters attached to the derivatives causes the solution of the given problem to exhibit boundary ...

Wake properties and power output of very large wind farms for different meteorological conditions and turbine spacings: a large-eddy simulation case study for the German Bight [PDF]

open access: yesWind Energy Science, 2022
Germany's expansion target for offshore wind power capacity of 40 GW by the year 2040 can only be reached if large portions of the Exclusive Economic Zone in the German Bight are equipped with wind farms.

Effects of Surface Roughness on Shock-Wave/Turbulent Boundary-Layer Interaction at Mach 4 over a Hollow Cylinder Flare Model

open access: yesFluids, 2022
Although it is understood that surface roughness can impact boundary layer physics in high-speed flows, there has been little research aimed at understanding the potential impact of surface roughness on high-speed shock-wave/boundary-layer interactions ...

Numerical study of the effect of sidewalls on shock train behaviour

open access: yesFlow, 2023
Strongly coupled sequences of shock waves, known as shock trains, are present in high-speed propulsion systems, where the presence of sidewalls substantially modifies the boundary layer thickness, skin friction and streamwise pressure distribution.

The theoretical model of interaction between the baroclinic boundary layers of atmosphere and ocean

open access: yesVietnam Journal of Mechanics, 1980
Presenting the theoretical model of the atmospheric and oceanic baroclinic boundary layers by interaction. Baroclinic effects of two boundary layers are described by the horizontal gradients of air temperature and water density in the equations of ...

Transition in hypersonic boundary layers

open access: yesAIP Advances, 2015
Transition and turbulence production in a hypersonic boundary layer is investigated in a Mach 6 wind tunnel using Rayleigh-scattering visualization, fast-response pressure measurements, and particle image velocimetry.
