MULTI-STRATIFIED EFFECTS ON STAGNATION POINT NANOFLUID FLOW WITH GYROTACTIC MICROORGANISMS OVER POROUS MEDIUM

Abstract

The present investigation focuses 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 as 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 the fifth order Runge-Kutta-Fehlberg method with shooting technique. A graphical view of the velocity, temperature, concentration, and density of the microorganism-profile-concerned parameters are discussed in detail. A comparison with the local Nusselt number for distinct values of the Prandtl number reveal the validity of current results. 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.
