Near-field thermal emission between corrugated surfaces separated by nano-gaps
(Elsevier, 2015)
Near-field thermal radiation with its many potential applications in different fields requires a thorough understanding for the development of new devices. In this paper, we report that near-field thermal emission between ...
A retrospective view on‘‘3-dimensional radiation in absorbing, emitting and scattering media using discrete-ordinates approximation’’by J.S.Truelove
(Elsevier, 2010-06)
Discrete-ordinates (DO) approximations to the radiative transfer equation in three- dimensional enclosures have extensively been used during the last three decades. The 1988 paper by Truelove [1] is one of the pioneering ...
Plasmonic responses of metallic/dielectric core-shell nanoparticles on a dielectric substrate
(IOP Publishing, 2019-06)
The effect of material selection on the plasmonic response and local absorption are evaluated for core- shell nanoparticles placed over a BK7 glass substrate. Eight different core-shell pairs are studied using the vectorized ...
Coexistence of multiple regimes for near-field thermal radiation between two layers supporting surface phonon polaritons in the infrared
(American Physical Society, 2011)
We demonstrate the coexistence of different near-field thermal radiation regimes between two layers supporting surface phonon polaritons (SPhPs) in the infrared. These regimes existwhen the distance of separation between ...
The effect of nanoparticle type and nanoparticle mass fraction on heat transfer enhancement in pool boiling
(Elsevier, 2017-06)
Determining the heat transfer performance with nanofluids is of cardinal importance in the utilization of nanofluids in thermal systems. This study presents an experimental investigation on nucleate pool boiling heat ...
Experimental study on heat transfer of multi-walled carbon nanotubes/water nanofluids in horizontal microtubes
(ASME, 2016)
In this study, heat transfer characteristics of multi-walled carbon nanotube based nanofluids were investigated in horizontal microtubes with outer and inner diameters of ∼1067 and ∼889 μm, respectively. Carbon nanotubes ...
Optimization of spectrally selective Si/SiO2 based filters for thermophotovoltaic devices
(Elsevier, 2017-08)
Design of a spectrally selective filter based on one-dimensional Si/SiO2 layers is considered for improved performance of thermo-photovoltaic devices. Spectrally selective filters transmit only the convertible radiation ...
A design tool for direct and non-stochastic calculations of near-field radiative transfer in complex structures: The NF-RT-FDTD algorithm
(Elsevier, 2017)
Advances in nanotechnology and nanophotonics are inextricably linked with the need for reliable computational algorithms to be adapted as design tools for the development of new concepts in energy harvesting, radiative ...
Increasing the stability of nanofluids with cavitating flows in micro orifices
(AIP, 2016)
One of the most critical challenges for nanofluids in practical applications is related to their stability and reusability since a gradual agglomeration of nanoparticles in nanofluids occurs with time and is accelerated ...
Near to far-field thermal emission by nanoparticles on a substrate: Evaluation of effective medium theory
(The Optical Society, 2014)
We study the near to far-field thermal emission of a thin SiC film with/without nanospheres placed upon it. We show that Effective Medium Theorem produces questionable results when approximating emission and absorption ...
