Numerical analysis of roll waves generation on non-Newtonian fluids flowing down an inclined plane
This article aims to determine roll waves generation criteria for mudflow events. A representative system of equations to mudflows is reached through Cauchy's equations (mass and momentum conservation) with proper stress ...
Three-dimensional transient complex free surface flows: Numerical simulation of XPP fluid
In this paper we present a finite difference MAC-type approach for solving three-dimensional viscoelastic incompressible free surface flows governed by the eXtended Pom-Pom (XPP) model, considering a wide range of parameters. ...
Steady Flows Of Cosserat-bingham Fluids
Electrokinetic flow of non-Newtonian fluids in microchannels
A theoretical description of the electrokinetic flow of non-Newtonian fluids through slit and cylindrical microchannels is presented. Calculations are based on constitutive models of the fluid viscosity, and take into ...
Output pressure and efficiency of electrokinetic pumping of non-Newtonian fluids
Theoretical expressions of the flow rate, output pressure and thermodynamic efficiency of electrokinetic pumping of non-Newtonian fluids through cylindrical and slit microchannels are reported. Calculations are carried out ...
Condition for the incipient motion of non-cohesive particles due to laminar flows of power-law fluids in closed conduits
The results of an experimental study on the condition of incipient transport of non-cohesive particles due to the flow of a power-law fluid in a rectangular pipe are presented in this article. The pipe can change its ...
Effect of the solvent viscosity on pure electro-osmotic flow of viscoelastic fluids
In this work the fully-developed steady channel flow of the homogeneous polymer solution studied in  is revisited and a completely new analytical solution is proposed which is devoid of the limitations of the previous ...
An evaluation of three upwinding approximations for numerical modeling the flow in tubular membrane of Newtonian and non-Newtonian fluids
(ELSEVIER SCIENCE INC, 2011)
In this paper, the laminar fluid flow of Newtonian and non-Newtonian of aqueous solutions in a tubular membrane is numerically studied. The mathematical formulation, with associated initial and boundary conditions for ...
