Bioconvection-enhanced oblique motion of chemically reactive Oldroyd-B liquid over a convectively heated elastic surface
The present study focuses on the investigation of bioconvection applications, shedding light on the significant implications for environmentally friendly and sustainable ‘green’ fuel cell technologies. In this context, the study paves the way for further exploration of the Oldroyd-B fluid model in the presence of gyrotactic microorganisms. The analysis delves into the mixed convection of the Oldroyd-B fluid with gyrotactic microorganisms, exploring the effects of an elastic surface and magnetic field interactions. Notably, the study considers the influence of chemical reaction processes, convective heating, and thermal radiation, enhancing our understanding of these complex phenomena. The governing two-dimensional equations for motion, momentum, mass, and energy were normalized using nonlinear system-wide ordinary differential equations through appropriate transformation methods. The resulting solution for this intricate physical problem was obtained using the bvp4c method, and its validity was confirmed by comparing it with previously reported findings in the literature. The study indicates that higher porosity and magnetic parameters significantly influence velocity profiles. Meanwhile, the temperature profile improves, and the thermal field is enhanced by Brownian diffusion and radiation variables. Additionally, the Peclet number affects the density of microorganisms. Furthermore, an increase in thermophoresis significantly reduces the wall heat transfer rate for both radiation and non-radiation cases.
