Abstract
Thermal radiations and effective characteristics of the nanoparticles play a vibrant role in the heat transfer enhancement. This work aims to investigate the influence of thermophysical characteristics of nano-diamond (ND) and silver (Ag) nanoparticles on the heat transfer intensifications in the nonlinear radiative and dissipative flow over an arched geometry. A self-similar coupled nature of the nanofluid model is acquired via similarity transformations. Furthermore, the mathematical treatment of the model is carried out by the RK scheme. Moreover, stimuli of various pertinent flow parameters on the velocity, heat transfer, streamlines, and isotherms are examined graphically.
