Mathematical modeling and chemical conduct considering non-Newtonian nanofluid by utilizing heat flux features

In the current era of nanotechnology, the design of biological devices requires efficient transmission of energy among the components. Computational studies are always prerequisite for general models. In view of this importance, this paper investigated the characterizations regarding the steady flow of 2D Oldroyd-B nanofluid in the presence of thermal radiation (nonlinear) over a radially stretched sheet. Buongiorno revised nanofluid relation of the nanomaterial is instigated in precise modeling. For the mechanism of mass transmission, we utilized features of constructive–destructive prescription. As a result of modeling, the raised PDEs are converted into ODEs by appropriate transformations. The numeric scheme BVP4C is utilized for the solutions. The physical variables of the assumed flow pattern are shown graphically with the significance of the involved parameter. Besides, the prescribed investigation explored the significant impact by involved physical parameters along with the declining conduct influenced by chemical reaction parameters on the considered model. Moreover, the numerical outcomes of surface drag force and the transfer rate of heat–mass are tabulated for numerous sets of physical parameters. The improvement of these results is guaranteed by comparing it with existing techniques.
