Multi- Stratified Effects on Stagnation Point Nanofluid Flow with Gyrotactic Microorganisms over Porous Medium

Abstract

Present investigation focus on the intricate interplay of multiple stratified effects on the stagnation point nanofluid flow with gyrotactic microorganisms across a porous medium. The study encompasses a comprehensive numerical analysis, examining the impacts of varying parameters such stratification parameters, porosity etc. on the flow characteristics. The gyrotactic behavior of microorganisms further adds complexity to the analysis. The findings contribute to a deeper understanding of the combined effects and their consequences on heat and mass transfer within the system. Such insights hold relevance in various engineering and environmental applications, including biofuel production and water treatment processes. Numerical solutions are obtained via fifth order Runge-Kutta-Fehlberg method with shooting technique. Graphical view of velocity, temperature, concentration and density of microorganism profile concerned parameters are discussed in details. Comparison with local Nusselt number for distinct values of Prandtl number considered to reveal the validity of current result. The temperature, concentration and density of microorganism fields lessened with enhancement of thermal, solutal and motile stratification parameters. Also concentration field boosts with enhancement of thermophoresis and Brownian motion parameter.
