AB - The current article discusses the heat transfer characteristics of
ferromagnetic liquid over an elastic surface with the thermal radiation and
non-Fourier heat flux. In most of the existing studies, the heat flux is considered as constant, but whereas we incorporated the non-Fourier flux to get the
exact performance of the flow. Also, we excluded the PWT and PHF cases
to control the boundary layer of the flow. The governing equations related to
our contemplate are changed into non-linear ordinary differential equations
(ODE’s) by utilizing appropriate similarity changes, which are at the point
enlightened by Runge–Kutta based shooting approach. The equations are
broken down concerning boundary conditions and to be explained prescribed
wall temperature (PWT) and prescribed heat flux (PHF) cases. The impacts
of diverse non-dimensional physical parameters on velocity and temperature
profiles are laid out graphically. Also, the assortment of skin friction and local
Nusselt number for both PWT and PHF cases for various assessments of
non-dimensional parameters have been sorted out. Towards the wrap-up of
the examination, we suspect that the friction factor coefficient is higher in the
PWT case compared to the PHF case. This result helps to conclude that the
flux conditions are useful for cooling applications.
