Original abstract
Background: Research on heat and mass transfer in Casson hybrid carbon nanotubes (HCNTs) has attracted enhancing attention due to their improved thermal properties and industrial importance. The present results have potential applications in heat exchangers, boilers, air conditioning, radiators and solar desalination. Objective: Motivated by these applications, this study examines the influence of magnetohydrodynamics (MHD) Darcy–Forchheimer flow of water based Casson HCNTs over a stretching surface (SS). This model includes viscous dissipation, slip and convective boundary conditions (BCs) and nonlinear thermal radiation (TR). The modified Buongiorno nanofluid (NF) model is employed to evaluate the influence of thermophoresis and Brownian motion. Methodology: The fundamental equations are simplified into nonlinear ordinary differential equations (ODEs) using suitable transformation variables. The transformed equations are solved by numerical computation using the Matlab bvp4c technique. The consequences of numerous physical parameters is demonstrated graphically. The results are validated using published benchmark solutions. Findings: The key finding of this research is that the primary and secondary velocity profile reduces when the value of injection/suction, Casson, porosity parameters is improved. The temperature profile augments as the values of radiation parameter and thermal Biot number enhances while it declines when boosting the value of injection/suction parameter. The NF concentration profile mounts when elevating the values of solutal Biot number and weakens for chemical reaction (CR) parameter. The streamline plots indicate that the velocity profile suppresses as improving the suction/injection parameter. Notably, as the porosity parameter ( λ ) augments 0 to 4, the skin friction coefficient (SFC) for both x and y − directions exhibit an enhancement of nearly 60% for hybrid nanofluid (HNF) and 40% for NF.
