Abstract
Investigating the characteristics and distinctive qualities of non-Newtonian fluids, the Sutterby model magnificently represents the dilute polymer solution. Different advantages of diluted polymeric solutions are found in polymerized melts, agricultural sprayers, clay coaters, cleansing products and many more. The purpose of this paper is to demonstrate a numerical solution of heat and mass transfer for a 3D study flow of Sutterby fluid over a bidirectional expansion surface. The heat generation/absorption, thermophoretic and thermal radiation effects are also analyzed. The nonlinear main problem is enhanced and transformed into a symmetrical model by using the similarity approach. To solve our creating problem numerically, we use the bvp4c technique. The effects of the obtaining results are discussed in detail and plotted on the basis of physical parameters. An increase in the stretching parameter values can indicate a decline in the concentration field and also decrease the consequent concentration boundary layer thickness. There is a rapid decay of the concentration field in accordance with the thermophoretic parameter compared to the Schmidt number.
