Thermal stratification effect on gravity driven transport of hybrid CNTs down a stretched surface through porous medium

The purpose of the current article is to explore the impact of thermal stratification and medium porosity on gravity-coerced transport of hybrid carbon nanotubes down an upright extending sheet inspired by a constant applied magnetic field along with heat transfer investigation in existence of thermal radiation, viscous dispersal, and joule heating effect. Rectangular coordinates are chosen for the mathematical interpretation of the governing flow problem. Homothetic analysis is employed for the sake of simplification process. The reduced system of coupled nonlinear differential equations is dealt numerically by dint of computational software MATLAB inbuilt routine function Bvp4c. The numerical investigation is carried out for the distinct scenarios namely, (i) Presence of favorable buoyancy force, (ii) Case of purely forced convection and (iii) Presence of opposing buoyancy force. Significant Findings: The key findings include that the presence of hybrid carbon nanotubes and medium porosity contributes significantly to upsurging surface shear stress magnitude whereas, external magnetic field and velocity slip effects in an altered manner. The present study may be a benchmark in study of fueling process in space vehicles and space technology.

Automated summary

The purpose of this article is to investigate the influence of thermal stratification and medium porosity on the gravity-driven transport of hybrid carbon nanotubes on an upright extending sheet under the influence of a constant applied magnetic field, as well as the effects of thermal radiation, viscous dispersal, and joule heating. The mathematical interpretation of the governing flow problem is done using rectangular coordinates, and homothetic analysis is employed for simplification. The numerical investigation is carried out using the MATLAB software. The key findings of the study show that the presence of hybrid carbon nanotubes and medium porosity significantly increase the surface shear stress magnitude, while the external magnetic field and velocity slip effects are altered. This study may serve as a benchmark for the fueling process in space vehicles and space technology.
