Abstract

This investigation presents novel applications for bioconvection flow of non-Newtonian fluid with diverse flow features. The developed unsteady bio-nano-transport model is formulated under the influence of some novel features such as variable thermal conductivity, heat absorption/generation and activation energy. In contrast to typical investigations, the flow has been originated by accelerated porous plate which conferred the suction and injection phenomenon. The thermal aspects of magnetized nanoparticles are evaluated by employing prestigious Buongiorno’s model. The flow model is constituted via partial differential equations for which dimensionless form is availed before develop the analytical expressions. The convergent technique namely homotopy analysis procedure is followed to suggest the solution. The validation of solution has been done by comparing it with already reported investigations and finds an excellent accuracy. The rheological characteristics of Eyring Powell fluid and thermal features of nanoparticles against involved control parameters are explained through various graphs. The reported results may contribute effective role in enhancement of thermal processes, cooling phenomenon, bio-fuels etc.
