A stratified MHD flow of Eyring‐Powell fluid containing gyrotactic microorganisms through a stretching sheet with mixed convection

Abstract

AbstractThe aim of this effort is to examine the steady, laminar, and incompressible flow of Eyring‐Powell fluid containing gyrotactic microorganisms through a stratified stretching surface. For stabilizing the distributed nanoparticles through bioconvection, which is tempted by magnetic field and buoyancy forces, the microorganisms’ theory is utilized. The nonlinear system of equations is treated with a semi‐analytical approach. Convergence of series solutions of the nonlinear system is displayed. The variations in momentum, concentration, thermal and motility distributions are exhibited graphically. Sherwood number, skin friction, motile density number, and Nusselt number are exhibited numerically in tabular forms. It has been found that the augmenting the thermal stratification, mass stratification, and motile density stratification factors have retarded the thermal, mass, and motile density of the microbes. Heightening Brownian motion, Schmidt number, and mass stratification parameter boost the Sherwood number, while reduces with thermophoresis constraint. The rise in concentration difference factor and Peclet number intensify the motile density number, while the accelerating values of stratification parameter of motile density and bioconvective Lewis number decline the motile density number.
