Characterization of Commercial Thermoelectric Modules for Precision Heat FLux Measurement
Jacob Crossley, A. N. M. Taufiq Elahi, Mohammad Ghashami +1
In this article, we present a cost-effective approach to the precision measurement of heat flux using commercial thermoelectric modules (TEMs). Two different methods of measuring h…
First-principles calculations of phonon transport across a vacuum gap
Takuro Tokunaga, Masao Arai, Kazuaki Kobayashi +5
Phonon transport across a vacuum gap separating intrinsic silicon crystals is predicted via the atomistic Green's function method combined with first-principles calculations of all…
Extreme Near-Field Heat Transfer Between Gold Surfaces
Takuro Tokunaga, Amun Jarzembski, Takuma Shiga +2
Extreme near-field heat transfer between metallic surfaces is a subject of debate as the state-of-the-art theory and experiments are in disagreement on the energy carriers driving…
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…
Comprehensive Energy Balance Analysis of Photon-Enhanced Thermionic Power Generation Considering Concentrated Solar Absorption Distribution
A. N. M. Taufiq Elahi, Mohammad Ghashami, Devon Jensen +1
The present article reports a comprehensive energy balance analysis of a photon-enhanced thermionic emission (PETE) device when it is used for concentrated solar power (CSP) genera…
Revisiting Submicron-Gap Thermionic Power Generation Based on Comprehensive Charge and Thermal Transport Modeling
Devon Jensen, Mohammad Ghashami, Keunhan Park
Over the past years, thermionic energy conversion (TEC) with a reduced inter-electrode vacuum gap has been studied as an effective way to mitigate a large potential barrier due to…
Role of Acoustic Phonon Transport in Near- to Asperity-Contact Heat Transfer
Amun Jarzembski, Takuro Tokunaga, Jacob Crossley +6
Acoustic phonon transport is revealed as a potential radiation-to-conduction transition mechanism for single-digit nanometer vacuum gaps. To show this, we measure heat transfer fro…
Near-Field Enhanced Thermionic Energy Conversion for Renewable Energy Recycling
Mohammad Ghashami, Sung Kwon Cho, Keunhan Park
This article proposes a new energy harvesting concept that greatly enhances thermionic power generation with high e ciency by exploiting the near- field enhancement of thermal radi…
