Numerical computations for Buongiorno nano fluid model on the boundary layer flow of viscoelastic fluid towards a nonlinear stretching sheet

The viscoelastic fluid flow over a non linear stretching porous sheet is considered in this analysis. The case of suction and injection is also discuused. The effects of thermophoresis and brownain motion with viscous dissipation is taken into account. Under the flow assumptions, boundary layer approximation applied on the mathematical model and developed the partial differential equations. The similarity variable is applied on the partial differential equations which converted into ordinary differential equations. The dimensionless system further solved through numerical technique bvp4c method. The results of the current problem achieved after solving the problem which presented through graphs and table. Influence of numerous physical parameters on velocity function, concentration function and temperature function are manipulated through graphs. The tabular results are schemed to display skin friction and local Nusselt number. The higher values of Nb which enhanced the velocity profile but declines velocity profile due to higher values of Ec. The thermal thickness enhances due larger values of γ and Pr but thermal thickness declines due to higher values of Ec and Nt. The concentration profile enhances due to enhancing the values of Ec and Pr but concentration profile declines due to increasing the values of Nt. Nusselt number enhaced due to higher values of Ec,Sc and Nt but declines of higher values of Pr.
