Entropy generation with ion-slip influx on peristaltic transition of hyperbolic tangent nanofluid of motile gyrotactic microorganisms and modified Darcy-Forchheimer characteristic

In this theoretical paper, an investigation is conducted into the peristaltic transition of a hyperbolic tangent nanofluid that contains mobile gyrotactic microorganisms. This study examines the entropy generation resulting from magnetohydrodynamic (MHD) flow and heat transport. The analysis encompasses an anisotropically stenosed endoscope, which is influenced by Ion-slip, activation energy, viscous dissipation, Hall efficacy, Joule heating and entropy generation. The impacts of nonlinear thermal radiation and chemical processes with Soret and Dufour schemes are studied. The porous medium is described using a modified form of Darcy's principle involving a Forchheimer framework. The assumptions involve the extended wavelength besdes reduced Reynolds numeral. The homotopy perturbation strategy is employed to solve the resulting equations. The results show that the critical velocity rises as the local temperature Grashof numeral increases. Moreover, the study offers insights into the movement of digestive gastric fluid within the small intestine as the endoscope moves through.
