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 ...

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.

Thermal Conductivity of Powders [PDF]

Nature, 1949
ACCORDING to a note in Physical Abstracts1, R. L. Mullokandov2 finds that thermal conductivity of powders is practically due only to the convection in the surrounding gas, and that hence "a layer of smooth spherical particles in vacuum may be used as a good thermal insulator". This was discovered by M. Smoluchowski some forty years ago3.

Thermal conductivity of antigorite

, 2023
This repository contains experimental data on the thermal conductivity of antigorite at high pressures and temperatures as well as a self-written MATLAB script used to numerically model 2D thermal evolution of a sinking slab. These materials are presented in a manuscript submitted by Yu-Hsiang Chien, Enrico Marzotto, Yi-Chi Tsao, and Wen-Pin Hsieh ...

Thermal Conductivity of B-DNA [PDF]

The Journal of Physical Chemistry B, 2021
The thermal conductivity of B-form double-stranded DNA (dsDNA) of the Drew-Dickerson sequence d(CGCGAATTCGCG) is computed using classical Molecular Dynamics (MD) simulations. In contrast to previous studies, which focus on a simplified 1D model or a coarse-grained model of DNA to improve simulation times, full atomistic simulations are employed to ...

Shape sensitivity for a two-phase heat conduction problem considering nanoscale effects

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
Thermal design is essential when developing various types of technological devices, especially miniaturized electronic devices. Conventional thermal design methods that only focus on macrostructures can provide only limited improvements in electronic ...

The Electronic Thermal Conductivity of Graphene [PDF]

Nano Letters, 2016
Graphene, as a semimetal with the largest known thermal conductivity, is an ideal system to study the interplay between electronic and lattice contributions to thermal transport. While the total electrical and thermal conductivity have been extensively investigated, a detailed first-principles study of its electronic thermal conductivity is still ...

2D MHD Simulations of the State Transitions of X-Ray Binaries Taking into Account Thermal Conduction

Galaxies, 2019
Thermal conduction plays an important role in bimodal accretion flows consisting of high-temperature flow and cool flow, especially when the temperature is high and/or has a steep gradient. For example, in hard-to-soft transitions of black hole accretion

New Method for Solving the Inverse Thermal Conduction Problem (θ-Scheme Combined with CG Method under Strong Wolfe Line Search)

Buildings, 2023
Most thermal researchers have solved thermal conduction problems (inverse or direct) using several different methods. These include the usual discretization methods, conventional and special estimation methods, in addition to simple synchronous gradient ...
