The Zoo of Non-Fourier Heat Conduction Models [PDF]
, 2022 The Fourier heat conduction model is valid for most macroscopic problems. However, it fails when the wave nature of the heat propagation or time lags become dominant and the memory or/and spatial non-local effects significant -- in ultrafast heating (pulsed laser heating and melting), rapid solidification of liquid metals, processes in glassy polymers ...

Theories and heat pulse experiments of non-Fourier heat conduction
Communications in Applied and Industrial Mathematics, 2016 Abstract The experimental basis and theoretical background of non-Fourier heat conduction is shortly reviewed from the point of view of non-equilibrium thermodynamics. The performance of different theories is compared in case of heat pulse experiments.

Non-Fourier Heat Conduction in Carbon Nanotubes
ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 3, 2009 Fourier’s law is a phenomenological law to describe the heat transfer process. Although it has been widely used in a variety of engineering application areas, it is still questionable to reveal the physical essence of heat transfer. In order to describe the heat transfer phenomena universally, Guo has developed a general heat conduction law based on ...

Non-Fourier heat conduction in oil-in-water emulsions
International Journal of Heat and Mass Transfer, 2019 Abstract Emulsions have widely been used in various application, e.g. in energy system as a potential second refrigerant. However, there is a lack of comprehensive study on extraordinary effective thermal conductivity enhancement in the oil-in-water (O/W) emulsions, and effects of temperature and droplet size were not considered in the widely used ...

A new approximate-analytical method to solve non-Fourier heat conduction problems [PDF]
Kuwait Journal of Science, 2017 In this paper, the effect of laser as a heat source on a thin film was investigated. The non-Fourier heat conduction modelof Cattaneo-Vernotte was used for thermal analysis of the problem. The thermal conductivity was assumed temperaturedependent, which

Investigation of conduction to keyhole mode transition [PDF]
, 2012 There are two very distinct welding modes in laser welding, keyhole and conduction mode. The characteristics of keyhole laser welding; mainly high penetration, high productivity and high aspect ratio have led the industry to focus more on this mode.

Causality in non-fourier heat conduction
Journal of Physics Communications, 2022 Abstract We present a study of the causal response of non-Fourier heat conduction by introducing a dispersive generalized thermal susceptibility and show it obeys Kramers-Kronig relations. In particular, we discuss the Cattaneo-Vernotte and the dual-phase lag models.
