Chemical Reaction and Stefan blowing analysis of Eyring- Powell nanofluid over a stretched surface with Thermal Radiation

Abstract

This paper presents a comprehensive study on the magnetohydrodynamic flow of an Eyring-Powell nanofluid over a stretchable surface, focusing on the significant effects of chemical reactions, Stefan blowing, and thermal radiation. The research employs advanced numerical techniques and similarity transformations to convert critical partial differential equations governing momentum, concentration, and temperature into a manageable system of non-linear ordinary differential equations. The outcomes of critical physical parameters are acquired by engaging the built-in bvp4c solver in the MATLAB computational software. The computational approach utilized in this study is validated through a comparison with existing literature, showcasing a high degree of agreement with previous results. This reinforces the reliability of the numerical methods employed and the relevance of the findings. The profiles of velocity, temperature, and concentration as well as the related physiological traits that are used in the study have been identified. The intricate relationship between the skin friction coefficient, Sherwood number, and Nusselt number, and their impact on mass and heat transfer characteristics, has been a subject of extensive research in various fields, including fluid dynamics, heat transfer, and chemical engineering. Key results indicate that an increase in the thermal radiation parameter leads to a notable rise in temperature distribution, enhancing heat transfer rates. Specifically, the study finds that the temperature increases significantly with higher thermophoresis and Brownian motion parameters, which facilitate better thermal energy transfer. Additionally, the concentration field shows a substantial decrease with an increased chemical reaction rate, highlighting the impact of reaction kinetics on mass transfer.The study reveals that the inclusion of Stefan blowing significantly influences fluid motion, leading to increased velocity profiles due to the introduction of additional momentum into the boundary layer. This effect is crucial for applications requiring efficient fluid transport.
