Bioconvection entropy optimized flow of Reiner-Rivlin nanoliquid with motile microorganisms

Sohail A. Khan et al.

Summary: This study focuses on the hydromagnetic bioconvective chemically reactive flow of Reiner-Rivlin nanoliquid and analyzes the entropy generation. The thermal relation includes Joule heating, radiation, and dissipation. Soret effect in chemically reactive flow is examined. Nonlinear governing systems are solved using the ND-solve technique after appropriate transformations. Graphical analysis is conducted for velocity, microorganism field, entropy rate, thermal field, and concentration. The graphical descriptions for coefficient of skin friction, microorganism density number, heat transport rate, and concentration gradient are also studied. It is observed that the entropy rate increases with a higher magnetic parameter, while the velocity shows the opposite trend. Increasing temperature enhances thermophoresis and radiation. Radiation intensifies the entropy rate and heat transport rate. Similar effects of drag force and temperature are observed for the magnetic parameter. The concentration and mass transport rate increase with a higher Soret number. Variation in Brownian motion results in concentration decay. A larger Peclet number leads to a decrease in the microorganism field and an increase in the microorganism density number.
