Approximate analytical solutions to nonlinear peristaltic flow with temperature-dependent viscosity parameters: Application of multi-step differential transform method (MsDTM)

Abstract: This paper investigates the influence of temperature-dependent viscosity on peristaltic flow of a Newtonian fluid past a vertical asymmetric channel through a porous medium in the presence of heat and mass transfer. A mathematical model is analyzed under assumptions of long wavelength and small Reynolds number. The resulting system of coupled nonlinear differential equations with corresponding boundary conditions is computed in two different cases. In the first case (labeled as system I), all non-dimensional p… Show more

“…Therefore, from the above discussions, we conclude that the CP-Model case leads to unrealistic results, whereas the VP-Model shows real outcomes. Discussion on Some Previous Works Elogail and Elshekipy [28] caught sight of the necessity of treating the non-dimensional parameters that rely on viscosity in their definitions in the set of governing equations to be variables too. Consequently, this extra step has modified the set of governing equations (as in the VP-Model).…”

“…19,20 After considering the abovementioned studies, the vital role of this study is to present an original model for the influence of thermal radiation and temperature-dependent viscosity on peristaltic pumping of nanofluid models. It is worth mentioning that Elogail and ElShekhipy 29 have introduced the idea of the variable nondimensional parameters in a base fluid in peristaltic transport of a Newtonian fluid. We develop that idea in nanofluid models with a non-Newtonian fluid flow in a tapered asymmetric channel.…”
