ABSTRAKT

In this paper, entropy generation during heat and mass transfer in peristaltic Ellis fluid (blood) flow through a nonuniform channel is investigated. The walls of the channel are considered to be compliant. The governing equations for the Ellis fluid model, as well as the energy, concentration, and entropy equations are simplified using the approximation of long wavelength (0 << λ → ∞) and creeping flow regime (Re → 0). The solution for the resulting differential equations is obtained analytically, and closed form solutions are presented. Mathematical and graphical analyses of the velocity profile, temperature profile, concentration profile, and entropy profile are presented for the Schmidt, Eckert, Soret, Prandtl, and Brinkmann numbers, compliant wall parameters, and Ellis fluid parameters. It is observed that the fluid parameters provide a significant resistance to the velocity of the fluid.Moreover, the Eckert and Schmidt numbers show opposite impact on the concentration profile as compared to temperature distribution. The present investigation is also applicable in treatment of various diagnostic problems and different drug delivery systems in pharmacological, thermal, and biomedical engineering.
