...Girish Krishnan; Mohammad Parhizi; Mohsen Torabi; Ankur Jain The local thermal nonequilibrium (LTNE) model has been used widely for analyzing heat transfer during internal flow through porous media, including when a channel is only partially filled with a porous medium. In such problems, the Biot...

...C. Hemanth Kumar; B. M. Shankar; I. S. Shivakumara The onset of thermosolutal convection in a fluid-saturated porous medium in the presence of a horizontal pressure gradient and the Soret effect under the two-temperature model of local thermal nonequilibrium (LTNE) is investigated. The Darcy model...

... throughflow in a uniformly heated/cooled porous channel has been investigated under conditions of local thermal nonequilibrium (LTNE). The boundary planes are subject to symmetric wall heat fluxes. The intensity of the wall heating/cooling is associated with the Darcy–Rayleigh number, R , which can be either...

...Kun Yang; Kambiz Vafai Thermal conditions at the porous-fluid interface under local thermal nonequilibrium (LTNE) conditions are analyzed in this work. Exact solutions are derived for both the fluid and solid temperature distributions for five of the most fundamental forms of thermal conditions...

...Kun Yang; Kambiz Vafai The transient thermal response of a packed bed is investigated analytically. A local thermal nonequilibrium model is used to represent the energy transport within the porous medium. The heat flux bifurcation phenomenon in porous media is investigated for temporal conditions...

...D. A. Nield; A. V. Kuznetsov The onset of convection in a horizontal layer of a nanofluid is studied analytically. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis, and allows for local thermal nonequilibrium (LTNE) between the particle and fluid...
