Energy transfer in two-dimensional magnetohydrodynamic turbulence: formalism and numerical results

open access: yes, 2001
The basic entity of nonlinear interaction in Navier-Stokes and the Magnetohydrodynamic (MHD) equations is a wavenumber triad ({\bf k,p,q}) satisfying ${\bf k+p+q=0}$.

The Effects of CO2 Additional on Flame Characteristics in the CH4/N2/O2 Counterflow Diffusion Flame

open access: yesMolecules, 2021
The effects (chemical, thermal, transport, and radiative) of CO2 added to the fuel side and oxidizer side on the flame temperature and the position of the flame front in a one-dimensional laminar counterflow diffusion flame of methane/N2/O2 were studied.

Foerster resonance energy transfer rate and local density of optical states are uncorrelated in any dielectric nanophotonic medium [PDF]

open access: yes, 2015
Motivated by the ongoing debate about nanophotonic control of Foerster resonance energy transfer (FRET), notably by the local density of optical states (LDOS), we study an analytic model system wherein a pair of ideal dipole emitters - donor and acceptor

Preparation and characterization of an aluminum ammonium sulfate dodecahydrate-based composite phase change material with low supercooling and high thermal conductivity

open access: yesCase Studies in Thermal Engineering
Aluminum ammonium sulfate dodecahydrate (AASD) is a promising hydrated salt-type phase change material. However, its application is severely hindered by its large undercooling and low thermal conductivity.

Radiative heat transfer exceeding the blackbody limit between macroscale planar surfaces separated by a nanosize vacuum gap

open access: yesNature Communications, 2016
Evanescent coupling between surfaces separated by a distance smaller than the thermal wavelength can lead to radiative heat transfer greater than the blackbody limit.
