Ultrafast radiative heat transfer [PDF]

open access: yesNature Communications, 2017
AbstractLight absorption in conducting materials produces heating of their conduction electrons, followed by relaxation into phonons within picoseconds, and subsequent diffusion into the surrounding media over longer timescales. This conventional picture of optical heating is supplemented by radiative cooling, which typically takes place at an even ...

Analytical considerations of flow boiling heat transfer in metal-foam filled tubes [PDF]

open access: yes, 2012
Flow boiling in metal-foam filled tube was analytically investigated based on a modified microstructure model, an original boiling heat transfer model and fin analysis for metal foams.

Heat transfer coefficient saturation in superconducting Nb tunnel junctions contacted to a NbTiN circuit and an Au energy relaxation layer [PDF]

open access: yes, 2014
In this paper we present the experimental realization of a Nb tunnel junction connected to a high-gap superconducting NbTiN embedding circuit. We investigate relaxation of nonequilibrium quasiparticles in a small volume Au layer between the Nb tunnel ...

Numerical Study on Transient Heat Characteristics of a Rectangular Latent Heat Storage Vessel [PDF]

open access: yes, 1995
Transient characteristics of the rectangular latent heat storage vessel packed with shape-stabilized phase change (solid-liquid) material (PCM) are investigated numerically by solving the governing equations of both the PCM and the heat transfer medium ...

Combined conduction and natural convection cooling of offshore power cables in porous sea soil [PDF]

open access: yes, 2019
The power that can be carried by offshore power cables is often restricted by the temperature limit of the materials inside the cable. It is therefore essential to predict the heat transfer behavior of the dissipated power from the cable to the ...

Resonant photon tunneling enhancement of the radiative heat transfer [PDF]

open access: yes, 2004
We study the dependence of the heat transfer between two semi-infinite solids on the dielectric properties of the bodies. We show that the heat transfer at short separation between the solids may increase by many order of magnitude when the surfaces are ...

Three-dimensional Navier-Stokes heat transfer predictions for turbine blade rows [PDF]

open access: yes
Results are shown for a three-dimensional Navier-Stokes analysis of both the flow and the surface heat transfer for turbine applications. Heat transfer comparisons are made with the experimental shock-tunnel data of Dunn and Kim, and with the data of ...

Natural convection heat transfer from two horizontal cylinders [PDF]

open access: yes, 2008
Natural convection heat transfer from a single horizontal cylinder and a pair of vertically aligned horizontal cylinders is investigated. Surface heat transfer distributions around the circumference of the cylinders are presented for Rayleigh numbers of ...

HEAT TRANSFER ENHANCEMENT IN LAMINAR CONVECTIVE HEAT TRANSFER WITH NANOFLUIDS

open access: yesProceeding of TMNN-2011. Proceedings of the International Symposium on Thermal and Materials Nanoscience and Nanotechnology - 29 May - 3 June , 2011, Antalya, Turkey, 2011
In order to utilize nanofluids in practical applications, accurate prediction of forced convection heat transfer of nanofluids is necessary. In the first part of the present study, we consider the application of some classical correlations of forced convection heat transfer developed for the flow of pure fluids to the case of nanofluids by the use of ...
