Computational Role of Autocatalytic Chemical Reaction in the Dynamics of a Ternary Hybrid Nanofluid Past a Rotating Stretching Surface

Due to its superior thermal conductivity and efficient thermal management, ternary nanofluids play a crucial role in electronic advance cooling systems, solar thermal collectors, managing efficiency of thermal exchangers, targeted drug delivery systems, and various technologies. An essential aspect of understanding complex systems is studying the interplay between fluid movement, heat transport, and chemical processes. Therefore, examining chemical reactions is vital for various industrial applications in environmental areas. Because of these applications, this study examines the impact of endothermic/exothermic chemical reactions on the flow of a ternary nanofluid across a rotating permeable-stretched surface. The governing equations are transformed into the system of ordinary differential equations (ODEs) and numerically tackled with the help of the Runge–Kutta–Fehlberg 4th 5th (RKF45) order scheme. The outcomes of pertinent constraints on their respective profiles are illustrated through graphs. The results show that the thermal profile diminishes for the exothermic case and enhances for the endothermic case in context to the activation parameter. Improvement in solid volume fraction will improve the rate of thermal distribution for both endo and exothermic cases. The rate of thermal distribution increases by about 3.22% from ternary nanofluid to nanofluid, while the rate of mass transfer is about 2.31%. The outcomes will help in chemical manufacturing, renewable energy technologies, material sciences, and designing and optimization of the delivery of drugs.
