Ensuring sustained thermal propagation is a crucial role in many industrial and systems since it facilitates the improvement of efficiency engineering engines machinery. Therefore, usage magnetized nanoparticles heat-carrying non-Newtonian fluid promising development for enhancement power energy. This paper uniquely contributes by comprehensively analyzing heat mass transfer characteristics Casson nanofluid subjected to bioconvection over disk. The study also explores detail interaction gyrotactic microorganisms, activation energy system. Similarity transformations have been used make governing partial differential equations (PDEs) dimensionless, which has then transformed them into ordinary equations. solution method utilized Shooting technique combined with Bvp4c solver MATLAB. Graphs drawn explain different parameters flow; also, other quantities, like motile microbes density Sherwood numbers, calculated are represented graphically. Furthermore, interplay mixed convection, buoyancy ratio, Rayleigh constant, resistivity due magnetization significantly influences distribution velocity nanofluid. Remarkably, that characterize microorganism profile attenuate said profile; therefore, they play very important shaping system dynamics. application phenomena spans diverse fields, ranging from healthcare environmental monitoring agriculture renewable energy, offering innovative solutions address complex challenges.
