Thermal and magnetic influences on the hybrid nanofluid flow over exponentially elongating/contracting curved surfaces in porous media: a comprehensive study

The performance of heat transportation fluids in thermal engineering applications enforces us to investigate the combined impacts of magnetisation and radiating heat considering a hybrid nanofluid flow. The transport phenomena of the proposed hybrid nanofluid through a curved surface in a porous medium are analysed by considering ferrite nanoparticles. The surface is preamble and expanding/contracting exponentially. Additionally, it is not wise to neglect the role of Joule dissipation since properties of magnetisation are involved in the proposed phenomena. To analyse the system, a suitable similarity rule is employed to change the governing equation into an ordinary equation. The resulting set of equations is then numerically solved by implementing the “Runge–Kutta” method associated with the “shooting technique”. The quantitative numerical values coincide with prior published work showing validation of the current result vis-à-vis the convergence criteria. However, the findings of the result reveal that the magnetisation and thermal radiation significantly improve the fluid flow and enhance the rate coefficients. Due to the impressive utility of the heat transport phenomenon in manufacturing various electronic devices, cooling of microchips, drug delivery processes, etc. the role of nanoparticles presents its vital role.
