Abstract

This research offers valuable insights for improving heat transfer and minimizing entropy generation in engineering systems that involve nanofluids and microorganisms. It investigates the unsteady squeezing bioconvection flow of a nanofluid between two parallel disks, with a focus on entropy generation, flow dynamics, heat transfer, and the concentration of both nanoparticles and microorganisms. The lower disk is stretched horizontally and subjected to suction, while the upper disk moves vertically, creating a squeezing effect. Temperature and concentration slip conditions are applied, and the problem is normalized using similarity transformations. To acquire numerical solution, the bvp4c approach is utilized. The influence of various physical parameters particularly squeezing, magnetic, suction, Brownian motion, thermophoresis, and mass transfer parameters associated with the concentration of nanoparticles and microorganisms on fluid velocity, temperature, concentration profiles, and entropy generation is analyzed. Findings suggest that increasing the suction parameter reduce fluid velocity, while the squeezing and magnetic parameters enhance the velocity near the upper disk and hinders it near lower disk. Furthermore, an increase in the Brownian motion and thermophoresis parameters results in a reduction in nanoparticle concentration, whereas both parameters contribute to an elevation in the temperature profile. The study also highlights the impact of various factors such as Brinkman number and mass transfer parameter on entropy generation, Bejan number and overall system’s efficiency.
