- Abstract
Gyrotactic microorganisms may be mobile ones that exist in surroundings, for instance oceans, pools, and reservoirs. The convective heat transfer due to the movement of these microorganisms in the base fluids is known as bio-convection. In this paper, the analysis of MHD bio-convection of nanofluid in the Γ -shaped enclosure with gyrotactic microorganisms inside is conducted. The effect of thermal Rayleigh number Rat (104–105), bio-convection Rayleigh number (10–100), Lewis number (0.1–0.9), and Peclet number (10 − 3 –10 − 1 ) on the natural convection (NC) and concentration of the micro-organisms (C) is investigated. The Navier–Stokes equations are used as the governing equations and are solved by Finite Element Method. The results reveal that Le may have a reverse impact on Nuavg (upto 42%); however, Pe has a positive impact on both Nuavg (upto 10%) and Shavg (upto 12%) and enhances heat transfer performance.
