Control of near-field radiative heat transfer based on anisotropic 2D materials
AIP Advances, 2018 In this work, we study the near-field radiative heat transfer between two suspended sheets of anisotropic 2D materials. It is found that the radiative heat transfer can be enhanced with orders-of-magnitude over the blackbody limit for nanoscale ...

Many-Body Radiative Heat Transfer Theory [PDF]
Physical Review Letters, 2011 In this Letter a N-body theory for the radiative heat exchange in thermally non equilibrated discrete systems of finite size objects is presented. We report strong exaltation effects of heat flux which can be explained only by taking into account the presence of many body interactions.

Porous materials for thermal management under extreme conditions [PDF]
, 2006 A brief analysis is presented of how heat transfer takes place in porous materials of various types. The emphasis is on materials able to withstand extremes of temperature, gas pressure, irradiation, etc., i.e.

Homogenization of a Conductive and Radiative Heat Transfer Problem [PDF]
Multiscale Modeling & Simulation, 2009 This paper is devoted to the homogenization of a heat conductionproblem in a periodically perforated domain with a nonlinear andnonlocal boundary condition modeling radiative heat transfer inthe perforations. Because of the critical scaling considered it isessential to use a method of two-scale asymptotic expansionsinside the variational formulation of

Mesoscopic Description of Radiative Heat Transfer at the Nanoscale [PDF]
Physical Review Letters, 2010 We present a formulation of the nanoscale radiative heat transfer (RHT) using concepts of mesoscopic physics. We introduce the analog of the Sharvin conductance using the quantum of thermal conductance. The formalism provides a convenient framework to analyse the physics of RHT at the nanoscale.

Fire, 2023 Trench fires on sloped terrain are always complicated due to the corresponding flame dynamics and heat transfer mechanisms. Flame attachment may increase the rate of fire spread (ROS) by enlarging the heating area of unburned vegetation.
