Self-similar structure of a hot magnetized flow with thermal conduction

open access: yes, 2012
We have explored the structure of hot magnetized accretion flow with thermal conduction. The importance of thermal conduction in hot accretion flows has been confirmed by observations of the hot gas surrounding Sgr $A^*$ and a few other nearby galactic ...

On the Efficiency of Thermal Conduction in Galaxy Clusters

open access: yes, 2018
Galaxy clusters host a large reservoir of diffuse plasma with radially-varying temperature profiles. The efficiency of thermal conduction in the intracluster medium (ICM) is complicated by the existence of turbulence and magnetic fields, and has received

Low-Temperature Coherent Thermal Conduction in Thin Phononic Crystal Membranes

open access: yesCrystals, 2016
In recent years, the idea of controlling phonon thermal transport coherently using phononic crystals has been introduced. Here, we extend our previous numerical studies of ballistic low-temperature heat transport in two-dimensional hole-array phononic ...

Heat conduction in deformable Frenkel-Kontorova lattices: thermal conductivity and negative differential thermal resistance

open access: yes, 2011
Heat conduction through the Frenkel-Kontorova (FK) lattices is numerically investigated in the presence of a deformable substrate potential. It is found that the deformation of the substrate potential has a strong influence on heat conduction.

Research progress of semiconductive shielding layer of HVDC cable

open access: yesHigh Voltage, 2019
As an indispensable part of high-voltage direct current (HVDC) cable, the semiconductive shielding layer plays the role of uniforming electric field in the cable.

Contactless Interface Using Exhaled Breath and Thermal Imaging

open access: yesSensors, 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.

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

open access: yesApplied 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 ...

The Self-limiting Nature of Jet-modulated Thermal Conduction in Cool Core Clusters

open access: yesThe Astrophysical Journal
Conduction as a mechanism for explaining the disrupted cooling-flow in galaxy clusters has been mostly discounted, as the process is inefficient at transporting heat all the way from the cluster into the core.

Anisotropic Thermal Conduction and the Cooling Flow Problem in Galaxy Clusters

open access: yes, 2009
We examine the long-standing cooling flow problem in galaxy clusters with 3D MHD simulations of isolated clusters including radiative cooling and anisotropic thermal conduction along magnetic field lines.

Effects of thermal conduction in sonoluminescence [PDF]

open access: yes, 1997
We show by numerical hydrodynamic calculations that there are two important effects of thermal conduction in sonoluminescence: (i) the bubble remains close to being isothermal during the expansion phase; and (ii) a cold, dense layer of air is formed at ...
