Stagnation point on the micropolar bioconvection nanofluid flow over inclined Riga plate: Keller box analysis

This study aims to examine chemical reactive agents on the micropolar of a nanoliquid containing motile bacteria spreading over an incline on the Riga plate. An electromagnetic actuator installed on the surface is called a Riga plate. It comprises an array of alternating electrodes arranged spanwise and a permanent magnet. Because of their exceptional thermal performance, nanoparticles are valued in heat transfer systems, material sciences, electronics, etc. Gyrotactic microorganisms are also included to prevent potential deposition. In addition, consideration is given to radiative flow, heat source/sink, and chemical and convective conditions. Moreover, a series of converted model equations are considered from the principal constitution equations, and the effective Keller box technique numerically solves these ordinary differential equations. The effects of thermal field, concentration of nanoparticles, velocity, microrotation, and motile density profiles are shown numerically and graphically. It is noted that the velocity microrotational fields exhibit dwindled behavior as material variables intensified. Velocity was enhanced with the increasing values of the mixed convection variable and the modified Hartman number. For larger values of the radiation factor, the thermophoresis number, the Biot number, and the Brownian motion magnitude, the thermal flow behavior is enhanced. The drag friction and motile density reduce in percentage form. The current inspection has many uses in technical fields of study, including electromagnetism miniature pumping and nanomechanics.
