Radiative thermal criticality and entropy generation of hydromagnetic reactive Powell-Eyring fluid in saturated porous media with variable conductivity
Salawu, S. O.; Kareem, R. A.; Shonola, S. A. - In: Energy Reports 5 (2019), pp. 480-488
Theoretical study of inherent irreversibility and thermal runaway of an exothermic reactive Eyring-Powell fluid flow through a saturated porous fixed horizontal channel with thermal radiation and variable electrical conductivity is investigated. The reactive conducting fluid under bimolecular...

Modelling of non-Newtonian fluids
Křen, Jiří; Hynčík, Luděk - In: Mathematics and Computers in Simulation (MATCOM) 76 (2007) 1, pp. 116-123
The problem of the non-Newtonian fluid flow is solved. The basic equations are derived based on the Newtonian fluid flow but using special constitutive equation for the viscosity. The spatial discretization is done using the finite element method (FEM). The algorithm is tested on a simple axial...

Spreading of non-Newtonian fluids and surfactant solutions on solid surfaces
Rafaı¨, Salima; Bonn, Daniel - In: Physica A: Statistical Mechanics and its Applications 358 (2005) 1, pp. 58-67
The spreading of Newtonian fluids onto smooth solid substrates is well known; the speed of the contact line is given by a competition between capillary driving forces and viscous dissipation, yielding Tanner's law R∝t1/10. Here, we study the spreading of droplets of complex fluids having...

Stable–unstable crossover in non-Newtonian radial Hele–Shaw flow
Obernauer, S; Drazer, G; Rosen, M - In: Physica A: Statistical Mechanics and its Applications 283 (2000) 1, pp. 187-192
The miscible displacement of a non-Newtonian, shear thinning aqueous polymeric solution, by a Newtonian fluid in a radial Hele–Shaw cell is studied. Experiments where the Newtonian fluid viscosity is tuned to lie between high and low shear rate asymptotic apparent viscosities of the polymeric...
