Numerical examination of the chemically reactive MHD flow of hybrid nanofluids over a two-dimensional stretching surface with the Cattaneo–Christov model and slip conditions

Abstract Energy deficiency is one of the most challenging issues of the present world due to its increasing demand in industrial and technological processes. To address this issue, energy efficiency improvement is essential. Hybrid nanofluids have significant applications in the industrial and engineering sectors because of their higher thermal conductivity compared to conventional nanofluids. Keeping these important applications in mind, this work investigates the two-dimensional magnetohydrodynamic hybrid nanofluid flow on shrinking/stretching sheets under the impact of the Cattaneo–Christov model, suction/injection, thermal radiation, and slip effects. The hybrid nanofluid is formed by mixing nanoparticles of copper and alumina with a base fluid. The main equations are converted to a dimensionless form using appropriate variables. The model is evaluated by using the bvp4c built-in code in MATLAB. As main outcomes of the work, it is revealed that the increasing magnetic parameter enhances the skin friction of hybrid nanofluids; however, a reverse influence is noticed in the velocity curve. An upsurge in thermal radiation and Eckert number causes a substantial augmentation in the heat transfer rate, and a similar influence is observed in the temperature profile. The mass transfer rate shows a decreasing behavior through growth in chemical reactions and the Schmidt number. This investigation offers comprehensive insights into optimizing heat transfer and fluid flow in various engineering and industrial applications, such as thermal management, manufacturing processes, chemical reactors, and microfluidic devices.
