Aligned Magnetic and Bioconvection Effects on Tangent Hyperbolic Nanofluid Flow Across Faster/Slower Stretching Wedge with Activation Energy: Finite Element Simulation

TLDR: In this article, the authors considered the time-dependent flow and improved thermal transport for tangent hyperbolic nanofluids across an extending wedge, where self-motile microorganisms were suspended in the fluid to avoid agglomeration of tiny particles.

Abstract: The underlying work includes the time-dependent flow and improved thermal transport for tangent hyperbolic nanofluids across an extending wedge. Self-motile microorganisms are suspended in the fluid to avoid agglomeration of tiny particles. Moreover, magnetic field, heat source, convectively heated boundary, and activation energy are considered. Mathematical formulation based on usual laws of conservation is non dimensionalized with emerging parameters through implementation of similarity transform to yield a corresponding set of ordinary partial differential equations. In the face of convective non linearity, a finite element discretization is harnessed to be coded and run on Matlab platform. The parametric calculation are carried out for faster and slower wedge. The rising strength of wedge angle, unsteadiness, and material law index recede the velocity distribution. The distribution of temperature upgrades directly against growing of Hartman number, thermophoresis, Biot number, material law index, and Brownian motion parameters. The concentration profile of nanoparticles decrease against Lewis number and activation energy, but it rises directly with higher input of activation energy. The computational results obtained through Matlab code blocks are corroborated with the existing literature and found to be a tolerable correlation.
