Case study of heat generation/absorption and activation energy on MHD hybrid nanofluid (GO-MoS2/water) flow owing to a rotatfing disk

Abstract

Research on hybrid nanofluid flow around spinning discs has potential uses in cooling technology, microfluidics, and energy systems, among other areas. Furthermore, in recent scientific and engineering endeavors, it is becoming more crucial to take sustainability and environmental impact into account when conducting nanofluid research. Heat transfer and heat generation/absorption has been examined due to activation energy and binary chemical reaction for the magnetohydrodynamic flow of hybrid nanofluid owing to rotating disk. Also, the introduction of Casson nanofluid has been made in this analysis. Temperature and concentration both show a rising tendency for rising Ha. Stronger temperature is correlated with higher Pr, while the opposite is true. With Nb and Nt, a stronger temperature distribution is observed. The concentration field for Higher γ shows a decreasing trend. The results show the rapid change for aggregated nanoparticles as compared to non-aggregated nanoparticles. The inclusion of hybrid nanofluid improves the temperature and thermal layers heat transfer in concerning nanofluid.
