The present study is an attempt to deal with hydrodynamic and thermal aspects of the incompressible Carreau fluid flow past a membrane consisting uniformly distributed aggregates porous cylindrical particles enclosing solid core which aims provide comprehensive impact non-Newtonian nature in filtration process through membranes. characteristic adopted describe mechanism pseudoplastic layout pattern separated into two distinct areas area adjacent particle considered as porous. However, region surrounding taken non-porous (clear region). Brinkman equation governs region, whereas regulated by Stokes equation. nonlinear governing equations different regions are solved using asymptotic series expansion terms small parameters, such Weissenberg number [Formula: see text] non-dimensional parameter text], for higher permeability material.

Non-newtonian fluid flow through three-dimensional disordered porous media.
We investigate the flow of various non-newtonian fluids through three-dimensional disordered porous media by direct numerical simulation of momentum transport and continuity equations. Remarkably, our results for power-law (PL) fluids indicate that the flow, when quantified in terms of a properly modified permeability-like index and Reynolds number, can be successfully described by a single (un...
متن کاملJeffery Hamel Flow of a non-Newtonian Fluid
This paper presents the Jeffery Hamel flow of a non-Newtonian fluid namely Casson fluid. Suitable similarity transform is applied to reduce governing nonlinear partial differential equations to a much simpler ordinary differential equation. Variation of Parameters Method (VPM) is then employed to solve resulting equation. Same problem is solved numerical by using Runge-Kutta order 4 method. A c...
متن کاملEntropy generation analysis of non-newtonian fluid in rotational flow
The entropy generation analysis of non-Newtonian fluid in rotational flow between two concentric cylinders is examined when the outer cylinder is fixed and the inner cylinder is revolved with a constant angular speed. The viscosity of non-Newtonian fluid is considered at the same time interdependent on temperature and shear rate. The Nahme law and Carreau equation are used to modeling dependenc...

15 صفحه اولGeneralized Newtonian Fluid Flow through a Porous Medium
We present a model for generalized Newtonian fluid flow through a porous medium. In the model the dependence of the fluid viscosity on the velocity is replaced by a dependence on a smoothed (locally averaged) velocity. With appropriate assumptions on the smoothed velocity, existence of a solution to the model is shown. Two examples of smoothing operators are presented in the appendix. A numeric...
