High precision simulation and analysis of non-Fourier heat transfer during laser processing

International Journal of Heat and Mass Transfer, 2021
Abstract With the rapid development of ultrashort-pulse laser heating and nanomaterials in science and engineering, the research on non-Fourier models to predict the anomalous heat conduction has attracted more and more attention. Among the existing non-Fourier models, the dual-phase-lag model can provide the best performance and it is more suitable ...

Non-Fourier bio heat transfer modelling of thermal damage during retinal laser irradiation

International Journal of Heat and Mass Transfer, 2013
Abstract Study of non-Fourier energy transport is important in various biomedical applications, in the understanding of heat transfer in biological tissues. One such biomedical application that involves non-Fourier heat conduction is laser irradiation of the retina, where a high heat flux is typically applied for a short period of time.

Heat Transfer Enhancement Feature of the Non-Fourier Cattaneo–Christov Heat Flux Model

Journal of Heat Transfer, 2021
Abstract Cattaneo–Christov heat flux model was proposed to remedy the weakness of the traditional Fourier heat flux model to maintain the finite travel time of heat. The literature is replete with numerical studies to understand the heat transfer enhancement property.

Numerical simulation of non-Fourier effects in combined heat transfer

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2010
The non-Fourier effects on transient and steady temperature distribution in combined heat transfer are studied. The processes of coupled conduction and radiation heat transfer in grey, absorbing, emitting, scattering, one-dimensional medium with black boundary surfaces are analysed numerically. The hyperbolic heat conduction equation is solved by flux

Microstructure-based non-Fourier heat transfer modeling of HIFU treatment for thyroid cancer

Computer Methods and Programs in Biomedicine, 2020
High intensity focused ultrasound is an emerging non-invasive technique for the thermal ablation of cancer. Modeling of high intensity focused ultrasound as a method to induce hyperthermia, by considering non-equilibrium convective heat transfer has been under-represented in the previous studies.

Rarefaction criterion and non-Fourier heat transfer in hypersonic rarefied flows

Physics of Fluids, 2010
As a hypersonic flow transits from continuous to more and more rarefied, both the bow shock wave and the boundary layer over a leading edge will gradually become thickening, touching, and interlacing with each other, characterizing the evolution of the flow field structure.
