Abstract
The objective of present paper is to examine the peristaltic flow of magnetohydrodynamic (MHD) Jeffrey fluid saturating porous space in a channel through rotating frame. Unlike the previous attempts, the flow formulation is based upon modified Darcy's law porous medium effect in Jeffrey fluid situation. In addition the impacts due to Soret and Dufour effects in the radiative peristaltic flow are accounted. Rosseland’s approximation has been utilized for the thermal radiative heat flux. Lubrication approach is implemented for the simplification. Resulting problems are solved for the stream function, temperature and concentration. Graphical results are prepared and analyzed for different parameters of interest entering into the problems.
Highlights
The flow induced by travelling waves along the channel walls has accorded the attention here due to its significance in physiological and industrial applications
There is ample information on peristalsis but some recent developments on the topic may be seen through the studies [3,4,5,6,7,8,9,10,11,12]
In particular the peristalsis of MHD fluid in presence of rotation is relevant with regard to certain flow cases involving the movement of physiological fluids for example the blood and saline water
Summary
The flow induced by travelling waves along the channel walls has accorded the attention here due to its significance in physiological and industrial applications. In particular the peristalsis of MHD fluid in presence of rotation is relevant with regard to certain flow cases involving the movement of physiological fluids for example the blood and saline water. The thermal diffusion effect is employed for isotope separation and in mixtures between gases with high molecular weight (H2, He) and of medium molecular weight (N2, air), the diffusion-thermo effect cannot be omitted Having all such viewpoints in mind the purpose here is to discuss the peristaltic flows of MHD non-Newtonian fluid in a rotating frame. We analyze the effect of rotation on MHD peristalsis of Jeffrey fluid in a porous medium. @p @x sB20u þ du dt ð17Þ at z 1⁄4 ÆZ: Non-dimensional variables can be put into the following forms: xà x l yà y l zà 1⁄4 z ; d pà d2p cml tà ct l uà 1⁄4 u ; c và 1⁄4 v ; c wà 1⁄4 w ; c
