A Thermopile Detector Based on Micro-Bridges for Heat Transfer

open access: yesMicromachines, 2021
A thermopile detector with their thermocouples distributed in micro-bridges is designed and investigated in this work. The thermopile detector consists of 16 pairs of n-poly-Si/p-poly-Si thermocouples, which are fabricated using a low-cost, high ...

Enhancing The Extremely High Thermal Conduction of Graphene Nanoribbons

open access: yesFrontiers in Physics, 2013
Graphene and Graphene nanoribbons (GNRs) are found to have superior high thermal conductivity favorable for high-performance heat dissipation. In this letter, by using molecular dynamics simulations, we show that constructing specific structure can ...

Nonlinear Heat Radiation Induces Thermal Rectifier in Asymmetric Holey Composites

open access: yesFrontiers in Energy Research, 2018
Asymmetric design and nonlinearity are essential to give rise to thermal rectification. In addition to the linear Fourier’s law of thermal conduction, we introduce the nonlinear thermal radiation following Stefan–Boltzmann law to asymmetric holey ...

Calculation methods of high temperature distribution within structural components and application of these methods to fire resistance assessment

open access: yesJournal of Civil Engineering and Management, 2001
Fire resistance of a building structure is one of important properties which describes the behaviour of the structure exposed to fire. Performance based on codes allows to use calculation methods.

Galaxy Motions, Turbulence and Conduction in Clusters of Galaxies [PDF]

open access: yes, 2010
Unopposed radiative cooling in clusters of galaxies results in excessive mass deposition rates. However, the cool cores of galaxy clusters are continuously heated by thermal conduction and turbulent heat diffusion due to minor mergers or the galaxies ...

Length-dependent thermal transport and ballistic thermal conduction

open access: yesAIP Advances, 2015
Probing length-dependent thermal conductivity of a given material has been considered as an important experimental method to determine the length of ballistic thermal conduction, or equivalently, the averaged phonon mean free path (l).

Stochastic transient analysis of thermal stresses in solids by explicit time-domain method

open access: yesTheoretical and Applied Mechanics Letters, 2019
Stochastic heat conduction and thermal stress analysis of structures has received considerable attention in recent years. The propagation of uncertain thermal environments will lead to stochastic variations in temperature fields and thermal stresses ...

Realization of Thermal Inertia in Frequency Domain

open access: yesEntropy, 2014
To realize the lagging behavior in heat conduction observed in these two decades, this paper firstly theoretically excludes the possibility that the underlying thermal inertia is a result of the time delay in heat diffusion.
