A Numerical Study of Small-Scale Longitudinal Heat Conduction in Plate Heat Exchangers

Energies, 2018
Longitudinal heat conduction has a significant effect on the heat transfer performance of plate heat exchangers, but longitudinal heat conduction is usually neglected in numerical studies and the thermal design of a heat exchanger.

Enhancing The Extremely High Thermal Conduction of Graphene Nanoribbons

Frontiers 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 ...

Contactless Interface Using Exhaled Breath and Thermal Imaging

Sensors, 2023
A new type of interface using a conduction hot spot reflecting the user’s intention is presented. Conventional methods using fingertips to generate conduction hot points cannot be applied to those who have difficulty using their hands or cold hands.

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

, 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 ...

Nonlinear Heat Radiation Induces Thermal Rectifier in Asymmetric Holey Composites

Frontiers 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 ...

The Law and Mechanism of the Effect of Surface Roughness on Microwave-Assisted Rock Breaking

Applied Sciences, 2023
In physical engineering, a rock surface, whether naturally or artificially formed, is rough. When irradiating rocks, microwaves produce reflections and diffractions on the surface of rough rocks, which significantly affect the absorption of microwave ...

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

Journal 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.

Length-dependent thermal transport and ballistic thermal conduction

AIP 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

Theoretical 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

Entropy, 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.
