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 fields. This article intends to perceive the Hall and ion-slip effects on Maxwell nanofluid carrying gyrotactic microorganisms and nanoparticles. The flow of fluid is well chosen in a non-Darcy porous ambience. Bioconvection phenomenon, thermal radiation, heat generation/absorptions effects are studied with first-order chemical reaction and a consistent magnetic field is administered within the numerical investigation. The governing nonlinear partial differential equations are converted into ordinary differential equations using similarity transformations. The 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 an improved thermal state of the fluid for the magnetic parameter, whereas the ion parameter is conversely impacted. The bioconvection Lewis number, Peclet number, and the microorganism's concentration difference parameter are observed to respond in downscale for the density of microorganism profile.
