Computational modeling and thermal analysis of magnetized nanofluid flow with physio-chemical interaction and chemical reaction between two non-parallel walls

The study of how energy undergoes changes in physio-chemical interactions involving Al₂O₃ and γ-Al₂O₃ with water and C₂H₆O₂ within converging and diverging channels is of great significance, given its potential applications in today's advanced technology. We have used two types of oxide nanoparticles, namely, Al₂O₃ and γ- Al₂O₃, with water and C₂H₆O₂. The purpose of this study is to investigate an innovative comparative magnetohydrodynamic (MHD) nanofluid flow and heat transport with the impact of thermal radiation on water and ethylene glycol (EG) suspended with Al₂O₃ and γ-Al₂O₃ nanoparticles. A novel comparison of concentration of Al₂O₃-H2O, γ-Al₂O₃-H₂O, and γ Al₂O₃-C₂H₆O₂ nanofluids is investigated under the influence of chemical reactions. The system of nonlinear ordinary differential equations was obtained via a similarity transformation and then solved using the homotopy analysis method (HAM) in Mathematica. The temperature and velocity profiles are obtained numerically for a range of controlling parameter values, including the volume percentage <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>φ</mml:mi></mml:mrow> </mml:math> of nanomaterials, the magnetic effect parameter M, the radiation parameter Rd, and Eckert number Ec in convergent/divergent channels. The concentration profiles of Al₂O₃-H₂O, γ-Al₂O₃-H₂O, and γ-Al₂O₃-C₂H₆O₂ tri-nanofluids are calculated numerically for governing parameter values, including those accounting for chemical reactions. The investigation's findings indicate that there is greater heat transport in γ-Al₂O₃-C₂H₆O₂ and γ-Al₂O₃-H₂O than in Al₂O₃-H₂O. We have demonstrated that there is good agreement between the current results and those found in the literature for various values of the magnetic field parameter, thermal radiation parameter, and nanoparticle volume fraction.
