Bio-Convection Eyring-Powell Hybrid Nanofluid Flow Over an Extended Sheet in the Existence of Chemical Reaction and Motile Microorganisms

Abstract

This mathematical analysis aims to examine the behavior of gyroscopic microorganisms to depict their role in transferring mass and heat in a hybrid nanofluid magnetohydrodynamic (MHD) that contains microorganisms and nanoparticles Cu and Al 2 O 3 while considering water as the basic fluid flowing over an extended surface with a chemical reaction. The presence of microorganisms increases the stability of suspended nanoparticles due to the bioconvection. The partial differential equations and the boundary conditions governing the problem were converted into ordinary differential equations with the help of some appropriate nondimensional transformations. The resulting equations were solved numerically using the MATLAB program function bvp4c. The effect of some important physical parameters on the profiles of velocity, concentration of nanoparticles, temperature, and motile microorganisms was also studied graphically. The coefficient of skin friction, mass and heat transfere rate, and microorganism density are enhanced when the convection constant parameter is improved. While the existence of a chemical reaction weakens the rate of heat transfere, it improves the coefficient of friction of the skin, the density of microorganisms, and the rate of mass transfer. A comparison was made between this work and previous works, and it was found that there is excellent agreement.
