The flow of a micropolar fluid through a porous channel with expanding or contracting walls

Abstract

Abstract:The flow of a micropolar fluid in a porous channel with expanding or contracting walls is investigated. The governing equations are reduced to ordinary ones by using similar transformations. Homotopy analysis method (HAM) is employed to obtain the expressions for the velocity fields and microrotation fields. Graphs are sketched for the effects of some values of parameters, especially the expansion ratio, on the velocity and microrotation fields and associated dynamic characteristics are analyzed in detail.

Numerical investigation of the flow of a micropolar fluid through a porous channel with expanding or contracting walls

“…We introduce the following similarity transformations that are motivated by the definition of the stream function (see Si et al [15])…”

A Note on Some Solutions of Copper-Water (Cu-Water) Nanofluids in a Channel with Slowly Expanding or Contracting Walls with Heat Transfer

“…Xinhui et al [12,13] analyzed the flow of non-Newtonian fluid in a porous channel with expanding or contracting walls. Many researchers have investigated the fluid flow behavior between expanding or contracting walls analytically as well as numerically under the various fluid flow conditions [14][15][16][17][18][19][20].…”

Multiple Solutions of Mixed Convective MHD Casson Fluid Flow in a Channel

“…The fluid flow in a channel has abundant practical applications in industry from mathematical and engineering point of view [1][2][3][4][5]. In particular, those fluids in which the shear stresses are not linear proportional to the velocity gradient are characterized as non-Newtonian fluids which are of much interest among the researchers.…”
