Heat transfer dynamics in the absorber plates of a flat-plate solar collector using both Fourier and revised non-Fourier analyses

open access: yesResults in Engineering
Recent years have seen an increased focus on non-Fourier heat conduction models for simulating microscale and ultrafast transient thermal processes. These models are particularly relevant in scenarios where classical Fourier theory fails to capture non ...

Two-layered electroosmotic flow through a vertical microchannel with fractional Cattaneo heat flux

open access: yesJournal of Taibah University for Science, 2021
The unsteady electroosmotic flow (EOF) of two layers of immiscible fluids through a vertical microchannel with heat transfer will be investigated. The channel is subjected to an alternating current (AC) electric field.

Quantum tight-binding chains with dissipative coupling [PDF]

open access: yes, 2015
We present a one-dimensional tight-binding chain of two-level systems coupled only through common dissipative Markovian reservoirs. This quantum chain can demonstrate anomalous thermodynamic behavior contradicting Fourier law.
