MHD thermosolutal marangoni convection heat and mass transport of power law fluid driven by temperature and concentration gradient

AIP Advances, 2015
This paper studies the magnetohydrodynamic (MHD) thermosolutal Marangoni convection heat and mass transfer of power-law fluids driven by a power law temperature and a power law concentration which is assumed that the surface tension varies linearly with ...

Operational Approach and Solutions of Hyperbolic Heat Conduction Equations

Axioms, 2016
We studied physical problems related to heat transport and the corresponding differential equations, which describe a wider range of physical processes. The operational method was employed to construct particular solutions for them.

Dynamics and Statistics of Reorientations of Large-Scale Circulation in Turbulent Rotating Rayleigh-B\'{e}nard Convection

, 2019
We present a direct numerical simulation to investigate the dynamics and statistics of reorientations of large-scale circulation (LSC) in turbulent rotating Rayleigh-B\'{e}nard convection (RRBC) for air ($Pr=0.7$) contained in a cylindrical cell with ...

Unified analytical framework for non-Fourier heat conduction in graded cylindrical media: Applications to perovskite solar cells and borehole heat exchangers

Case Studies in Thermal Engineering
This study develops the first unified analytical framework for transient, non-Fourier heat conduction in functionally graded (FG) cylindrical media within the dual-phase-lag (DPL) paradigm.

Cross-plane heat conduction in thin solid films [PDF]

, 2014
Cross-plane heat transport in thin films with thickness comparable to the phonon mean free paths is of both fundamental and practical interest. However, physical insight is difficult to obtain for the cross-plane geometry due to the challenge of solving ...

Nonequilibrium quantum fluctuation relations for harmonic systems in nonthermal environments

, 2013
We formulate exact generalized nonequilibrium fluctuation relations for the quantum mechanical harmonic oscillator coupled to multiple harmonic baths. Each of the different baths is prepared in its own individual (in general nonthermal) state.

Continuum-particle hybrid coupling for mass, momentum and energy transfers in unsteady fluid flow

, 2003
The aim of hybrid methods in simulations is to communicate regions with disparate time and length scales. Here, a fluid described at the atomistic level within an inner region P is coupled to an outer region C described by continuum fluid dynamics.

Research on macroscopic and microscopic heat transfer mechanisms based on non-Fourier constitutive model

International Journal of Heat and Mass Transfer, 2018
Abstract Based on the Cattaneo-Christov model and dual-phase-lag model, a novel constitutive model is proposed to study macroscopic and microscopic heat transfer mechanisms in the moving media. Formulated governing equation contains relaxation parameters and time fractional derivative with the highest order of 1 + α ...

Cattaneo-Christov heat and mass fluxes model of Casson fluid employing non-Fourier double diffusion theories with ion slip and Hall effects

Ain Shams Engineering Journal
It is vitally important to comprehend non-Newtonian fluids flow behaviour from an industrial perspective. Non-Newtonian fluids are needed for a number of industrial and technical processes, including the production of paper, photographic films, and ...
