Influence of activation energy in steady state hydro dynamic non-Newtonian nano fluid with mobile microorganisms

Abstract

The purpose of this article is to investigate the activation energy associated with bioconvection nano flow propagation via Riga plate with Arrhenius impact. Electricity flows through the fluid with a Lorentz force that alters in vertical direction. A Riga plate is considered when a magnetic electro force is applied. Casson and activation energy are included in the governing equations. The model is based on a Riga plate with a stretchy sheet that can represent bioconvection, the movement of microorganisms in two-phase nano-liquid flows. Novelty of this research is to explore the thermal and mass transport across a Riga plate of a Casson flow in steady, laminar, and MHD incompressible flow with bioconvection, and activation energy impacts. The governing PDEs are organized by the application of basic conservation laws, and they are subsequently transformed into equivalent ordinary differential equations. An evaluation of the present analysis is conducted using bvp4c, are displayed graphically. Results indicates magnetic field and Rayleigh bioconvection wither the velocity. Temperature profiles tend to be increased by Brownian motion.
