Abstract As industries rely more and on magnetohydrodynamic (MHD) systems for different uses in power, production, management of the environment, it becomes essential to optimize these operations. The study seeks improve effectiveness productivity cooling structures, chemical reaction reactors, contaminant control methods by investigating intricate interconnections. Because this, work scrutinizes endothermic/exothermic (EN/EX) processes, convective boundary conditions, pollutant concentration impacts MHD nanofluid circulation around a rotating sphere. governing equations based above assumptions are reduced into system ordinary differential solved numerically with Runge–Kutta Fehlberg’s fourth- fifth- order schemes. obtained numerical outcomes from scheme presented aid graphs, results show that rate mass transfer decreases an increase external local source solid volume percentage.

Abstract This study explores the optimization of Casson fluids, focusing on role ternary hybrid nanofluids in enhancing thermal efficiency industrial and engineering applications. Specifically, impact thermophoretic particles chemical reactions bioconvective nanofluid flow through a vertical microchannel embedded with porous media is examined. The governing equations are reduced using similarity transformations, resulting nonlinear solved Runge–Kutta–Fehlberg 4th 5th order method. findings reveal that increasing constraint leads to decrease nanoparticle concentration, highlighting forces particle movement deposition. Additionally, parameter causes reduction velocity, which observed affect overall fluid dynamics system. presence variable conductivity enhances field, suggesting temperature distribution can be significantly improved. Moreover, volume fraction distribution, indicating positive correlation between concentration efficiency. On other hand, results mass transfer rate, emphasizing trade‐off enhanced performance transport. These valuable for design advanced micro‐cooling devices, micro‐heat exchangers, micro‐pumps, macro mixing technologies, where both critical.
