摘要
A computational study of the magneto-hydrodynamic (MHD) non-linear convective Falkner-Skan flow over a stretching/shrinking wedge with variable suction and chemical reaction is presented in this article. A special geometric approach, "hyperbolic tangent fluid" which might have more realistic applications in the field of engineering materials is considered. Characteristics of heat transfer are explored under the precise heat flux environment. Nanofluid model comprises "Brownian motion" and "thermophoresis." To invoke suitable similarity variables, a step by step non-dimensional analysis is implemented. The nanofluid velocities, the relative temperature and its concentration are analyzed using video graphic footage. The expressions of Nusselt and Sherwood numbers are calculated and addressed comprehensively. It is seen that the Weissenberg parameter impedes fluid flow for static and moving (stretching/shrinking) wedge. It is also seen that an increment in reaction rate belittles the nanoparticle concentration while that of activation energy exhibits a reverse trend.
