Theoretical analysis of thermal characteristics of casson nano fluid flow past an exponential stretching sheet in Darcy porous media

The existent problem involves, the steady two-dimensional flow adjacent to boundary, mass as well as heat transfer of non-Newtonian Casson nano fluid in presence of an exponential stretching sheet. Then at this time work relating the BVP which forms a set of nonlinear normal differential equations, borrowed from a set of P.D.E's using similarity transformation, are cracked numerically with Runge-Kutta method of 4th order procedure with most efficient shooting technique. The brunts of an assortment of other dimensionless variables on temperature, velocity along with nano particle concentration are worked out, as well as the consequential values are depicted in graphical forms. The dimensionless variables under examination are Suction/Injection parameter F*w, Casson fluid Parameter β, Lewis number Le, Brownian Parameter Nb, Prandtl number Pr, Thermopheresis Parameter Nt, Porous parameter Kk*, whose brunt on Temperature profile G*(η), velocity profile F*(η), nanoparticle concentration profile H*(η) are exhibited in graphs in the course of Figs. 1 to 9 with detailed explanation.
