Abstract
Owing to improved thermal mechanism, various multidisciplinary applications of nanofluids have been inspected in engineering and industrial processes such as solar systems, heat transfer devices, nuclear reaction, chemical processes, extrusion applications, energy production, etc. Following such motivating applications, current exertion explores the enhanced thermal aspect of couple stress nanofluid consisting of motile microorganisms due to a bidirectional oscillatory stretched surface. The nanofluid bioconvection is established by the combined consequences of buoyancy forces and magnetic strength along with the collaboration of motile microorganisms and nanoparticles. Heat generation and thermal radiation aspects are utilized to deliberate the thermal transportation analysis. Additionally, chemical reaction and activation energy features are used for physical consequences. The formulated extremely nonlinear problem is condensed to a dimensionless form by following relevant transformations, and a further series solution is interpreted by the homotopic procedure. The observations perceived that velocity components and wall shear stresses periodically rise due to a couple of stress parameters. The present analysis accentuated that concentration distribution decays for reaction rate constant, while a conflicting trend is perceived for activation energy parameter.
