Effects of non-linear radiation and chemical reaction on Oldroyd-B nanofluid near oblique stagnation point flow

The oblique stagnation point flow of a viscoelastic nanofluid over a stretching cylinder is entertained in presence of non-linear thermal radiation and chemical reaction. Buongiorno's model is used to incorporate the significance of Brownian motion and thermophoresis diffusion. The governing partial differential equations in cylindrical polar coordinates are first transformed to system of ordinary differential equations using suitable transformations and dimensionless variables and then simulated numerically. Impact of interesting parameters on flow and heat transfer features is analyzed graphically and numerically. It is noticed that axial velocity increases with the retardation parameter while tangential velocity reduces. The magnitude of both axial and tangential velocities is large over stretching cylinder as compared to stretching sheet. Radiation parameter enhanced temperature profile and chemical reaction parameter rise the concentration profile.
