Abstract
A computational study on the diverging stagnation point of fluid flow is carried out over a convective plate. In this research, the unfaltering three-dimensional flow and heat transfer of non-Newtonian carbon nanotubes (CNTs) have been scrutinized. In order to analyze the stagnation point and rate of heat transfer, Xue’s model has been taken into consideration. Through similarity transformations, analytical unfolding of the governing coupled, non-linear, and ordinary differential equations has been performed. The most profoundly effective methods, termed the Keller Box method and the shooting method, are utilized. Using these propositions for CNTs of single-wall and multiwall carbon nano tubes, the results are co-related. For various values of material parameters, porosity, skin friction, temperature, solid volume fraction, Nusselt number, and Prandtl number, calculations have been put through. On observing, it is revealed that the porosity parameter has increased and both radial and azimuthal velocities decrease. When the stretching ratio parameter is increased while the azimuthal velocity is decreased, the radial velocity increases. It has also been discovered that sheer stress increases in direct proportion to porosity and stretching parameter. However, the rate of heat transfer shows inverse behavior against these parameters. The significant effects of these parameters are illustrated through graphs.
