Spatial DNS of an Isothermal Flat Plate Supersonic Turbulent Boundary Layer with/out Impinging Shock Wave

open access: yesJournal of Fluid Science and Technology, 2011
Spatial direct numerical simulation results are presented for transitional/turbulent supersonic isothermal flat plate boundary layers at M = 2.0 and impinging shock wave-boundary layer interactions.

From Nouns and Adjectives to Verbs: Base Effects on the Grammatical Behaviour of Denominal Verbs in Ancient Greek1

open access: yesTransactions of the Philological Society, EarlyView.
Abstract This paper investigates the role of semantic features of noun and adjective bases in determining the grammatical behaviour of Ancient Greek denominal and deadjectival verbs in *‐ye/o‐. The paper adopts a lexicalist framework (Rappaport Hovav & Levin 1998) and examines how the event schema, actionality, telicity and voice of derived verbs are ...

A primer on direct numerical simulation of turbulence - methods, procedures and guidelines

open access: yes, 2010
Direct Numerical Simulation (DNS) is the branch of CFD devoted to high-fidelity solution ofturbulent flows. DNS differs from conventional CFD in that the turbulence is explicitly resolved,rather than modelled by a Reynolds-averaged Navier-Stokes (RANS ...

Large-Scale Flow Structure in Turbulent Poiseuille Flows at Low-Reynolds Numbers

open access: yesJournal of Fluid Science and Technology, 2012
Direct numerical simulations of a spectral method are performed to study the turbulent channel flow at the low-Reynolds numbers, where the quasi-laminar and turbulent regions simultaneously appear and form the stripe pattern, which is floated downstream ...

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Study of Transition to Turbulence in a Supersonic Boundary Layer Using DNS and Transition Prediction

open access: yesJournal of Fluid Science and Technology, 2007
The current understanding of supersonic boundary layer transition is reviewed in this paper. The material focuses on bypass transition in a plane supersonic boundary layer. Recent advances in DNS and engineering prediction of transition are discussed. It

The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

The effect of upstream disturbance on the angle of sound emission in a supersonic round jet

open access: yesJournal of Fluid Science and Technology, 2014
The three-dimensional time-dependent compressible Navier-Stokes equations are numerically solved to study acoustic emission mechanisms in a supersonic round jet at high convective Mach numbers. A 5th-order compact upwind algorithm developed by Deng et al.
