The Influence of Bioconvection on the Electron Magnetohydrodynamic (EMHD) Fluid Flow

Influence of Bioconvection on the EMHD Fluid Flow

Abstract

In recent years, the important bioconvection phenomena with the use of nanoparticles has encountered basic industrial and technological applications. This study looked at how the bioconvection phenomenon affected the steady of EMHD nanofluid flow past an exponentially impermeable shrinking/stretching sheet. The system of partial differential equations is transformed into ordinary differential equations. We then employed similarity transformation in addition to non-dimensional quantities.  Additionally, the shooting technique in Maple is used to numerically solve the resulting equations.  We looked at how the model was affected by a few relevant parameters. The impact made by fluid over momentum, energy, concentration, along microorganism, including the Prandtl number, Peclet number, magnetic field, nanoparticle volume fraction parameter, electric conductivity, radiation parameter, bioconvection Lewis number, Weissenberg number, and more are shown graphically. By comparing the current results with the existing results in the literature, this technique is validated.  Variations in some parameters yield the following result: momentum profile is a decreasing function when acted upon by nanoparticle volume fraction, magnetic field, impermeability parameter and variable viscosity parameter. Nonetheless radiation, electricity, variable viscosity decreases the temperature of the system. While temperature of the system is increased by Prandtl number, magnetic field and impermeability parameter. For larger values magnetic field, electricity causes concentration profile to falls down. Reverse is the case for radiation parameter and Prandtl number.
