Second law analysis of laminar flow in a channel filled with saturated porous media: a numerical solution

Entropy, 2005
: This paper investigates entropy generation due to forced convection in a porous medium sandwiched between two parallel plates one of them being subjected to a uniform heat flux and the other one insulated.

Peristalsis of nonconstant viscosity Jeffrey fluid with nanoparticles

Results in Physics, 2016
Mixed convective peristaltic activity of variable viscosity nanofluids is addressed. Unlike the conventional consideration of constant viscosity; the viscosity is taken as temperature dependent.

Dissipative hydrodynamics for viscous relativistic fluids [PDF]

Physical Review C, 2006
Explicit equations are given for describing the space-time evolution of non-ideal (viscous) relativistic fluids undergoing boost-invariant longitudinal and arbitrary transverse expansion. The equations are derived from the second-order Israel-Stewart approach which ensures causal evolution. Both azimuthally symmetric (1+1)-dimensional and non-symmetric

The Thermal Performance Analysis of an Al₂O₃-Water Nanofluid Flow in a Composite Microchannel

Nanomaterials, 2022
Partial filling of porous medium insert in a channel alleviates the tremendous pressure drop associated with a porous medium saturated channel, and enhances heat transfer at an optimum fraction of porous medium filling.

Second Law Analysis of a non-Newtonian Laminar Falling Liquid Film Along an Inclined Heated Plate

Entropy, 2007
The second law analysis of heat transfer of a non-Newtonian, laminar fallingliquid film along an inclined heated plate is investigated. The upper surface of the liquidfilm is considered free and adiabatic.
