Abstract
This new work is initiated to explore the significance of nanoliquid introduction in the Walter’s B liquid, while the motion of the liquid is configured over a disk with non-zero thickness placed vertically in the presence of various physical behaviors, such as slips, joule heating, thermal radiation, heat generation/absorption and magnetic field along with homogeneous‐‐heterogeneous reactions are scrutinized. The notions of mixed convection as well as magnetic field are used to illustrate important physical features of the novel transient state problem. The problem is also represented using non-linear PDEs, which are then turned into ODEs using the suggested geometric conditions. By using a numerical framework, new physical behaviors are characterized in terms of velocity, temperature, concentration and displacement thicknesses. For well posed new problem, the order of the non-linear system is then reduced by applying the perturbation approach. It is found that as displacement thicknesses α and β increase, they tend to reach their asymptotic value ba→∞. For the same rising viscoelastic parameter values, the displacement thickness is found in reverse trends. The skin friction f″(0) fluctuation with respect to the viscoelastic parameter is deliberated with rising trend, when ba→∞ and vice -versa, for g″(0).
