Impacts of thermal aging and associated heat losses on the performance of a Pyromark 2500-coated concentrated solar power central receiver
Katie Bezdjian, Mathieu Francoeur
Pyromark 2500 is a widely used coating for concentrated solar power central receiver systems due to its high absorptivity, ease in application, and relatively low cost. Pyromark's…
Near-field thermal emission from metasurfaces constructed of SiC ellipsoidal particles
Lindsay P. Walter, Joseph C. McKay, Bart Raeymaekers +1
We model near-field thermal emission from metasurfaces structured as two-dimensional arrays of ellipsoidal SiC particles. The modeling approach is developed from fluctuational elec…
Orientation effects on near-field radiative heat transfer between complex-shaped dielectric particles
Lindsay P. Walter, Mathieu Francoeur
The effect of orientation on near-field radiative heat transfer between two complex-shaped superellipsoid particles of SiO2 is presented. The particles under study are 50 nm in rad…
Near-field radiative heat transfer between irregularly shaped dielectric particles modeled with the discrete system Green's function method
Lindsay P. Walter, Eric J. Tervo, Mathieu Francoeur
Near-field radiative heat transfer (NFRHT) between irregularly shaped dielectric particles made of SiO2 and morphology characterized by Gaussian random spheres is studied. Particle…
Revisiting the Figure of Merit of Concentrated Solar Power Receivers
A. N. M. Taufiq Elahi, Riley Crist, Vahid Hatamipour +3
The figure of merit (FOM) is a widely used metric to characterize the performance of concentrated solar power (CSP) receivers by comparing the amount of solar thermal energy retain…
A three-dimensional thermal model of the human cochlea for magnetic cochlear implant surgery
Fateme Esmailie, Mathieu Francoeur, Tim Ameel
In traditional cochlear implant surgery, physical trauma may occur during electrode array insertion. Magnetic guidance of the electrode array has been proposed to mitigate this med…
Experimental validation of a three-dimensional heat transfer model within the scala tympani with application to magnetic cochlear implant surgery
Fateme Esmailie, Mathieu Francoeur, Tim Ameel
Magnetic guidance of cochlear implants is a promising technique to reduce the risk of physical trauma during surgery. In this approach, a magnet attached to the tip of the implant…
Near-field radiative heat transfer between dissimilar materials mediated by coupled surface phonon- and plasmon-polaritons
Lei Tang, John DeSutter, Mathieu Francoeur
Near-field radiative heat transfer (NFRHT) between dissimilar materials supporting surface polaritons in the infrared is of critical importance for applications such as photonic th…
Design of an indium arsenide cell for near-field thermophotovoltaic devices
Daniel Milovich, Juan Villa, Elisa Antolin +4
An indium arsenide photovoltaic cell with gold front contacts is designed for use in a near-field thermophotovoltaic (NF-TPV) device consisting of millimeter-size surfaces separate…
A near-field radiative heat transfer device
John DeSutter, Lei Tang, Mathieu Francoeur
Recently, many works have experimentally demonstrated near-field radiative heat transfer (NFRHT) exceeding the far-field blackbody limit between planar surfaces. Due to the difficu…
Spectral redshift of the thermal near field scattered by a probe
Sheila Edalatpour, Vahid Hatamipour, Mathieu Francoeur
The physics underlying spectral redshift of thermally generated surface phonon-polaritons (SPhPs) observed in near-field thermal spectroscopy is investigated. Numerically exact flu…
