Source abstract
ABSTRACT The complex applications of nanofluids have made them a prominent subject in both engineering and scientific research, inspiring multidisciplinary modeling efforts supported by rapid developments in nanotechnology. The core purpose of the ongoing research is to examine the thermal behavior of carbon nanotubes (CNTs) ‐based hybrid nanofluids flowing along vertically stretching surfaces, considering the influence of Darcy–Forchheimer resistance and an inclined magnetic field. Owing to their remarkable thermal and electrical conductivity, along with high strength, stiffness, and toughness, CNTs have become an essential element in advanced engineering applications. A mathematical model is developed to examine the effects of porous media, magnetic fields, and nonlinear thermal radiation on velocity and temperature profiles in stagnation‐point hybrid nanofluid flow. By applying appropriate transformations, the governing equations are reduced to dimensionless system, which is then tackled numerically using the MATLAB bvp4c technique. The impacts of relevant flow parameters on the velocity and temperature fields are analyzed through graphical plots. During this exertion, results indicate that elevated mixed convection parameter intensifies fluid velocity, whereas thermal characteristics weaken under more substantial radiative effects. The local Nusselt number and skin friction coefficient are analyzed, with their variations and implications comprehensively evaluated. Additionally, it is evident from the results that hybrid nanofluids facilitate more rapid heat transfer compared to conventional nanofluids. This research provides valuable insights for optimizing energy systems and industrial operations by utilizing nanofluids and hybrid nanofluids for efficient thermal control.
