Hall and Ion Effects on Bioconvective Maxwell Nanofluid in non-Darcy Porous Medium

Abstract

Usage of nanoparticles along with bioconvection is one of the emerging techniques for heat transfer augmentation. The presence of Hall and ion effects becomes imperative and cannot be neglected on strong applied magnetic field. This article intent to perceive the Hall and ion slip effects on Maxwell nanofluid carrying gyrotactic micro-organisms and nanoparticles. The flow of fluid is well chosen in a non-Darcy porous ambience. Bioconvection phenomenon, thermal radiation, thermal generation and absorptions effects, first order chemical reaction and administered consistent magnetic field to reckon with in the numerical investigation. The governing non-linear partial differential equations are converted into ordinary differential equations using similarity transformations. Fifth order Runge-Kutta-Felhberg method with shooting technique is adapted to deal with the numerical solution. The graphical representation of pertinent parameters brings about reduced motion of the fluid and improved thermal state of the fluid for magnetic parameter, whereas ion parameter is noticed to impact in reverse. The bioconvection Lewis number, Peclet number and micro-organisms concentration difference parameter are observed to respond with downscale for density of micro-organism profile.
