Abstract

In this study, we discussed the enhancement of thermal conductivity  of elastico-viscous fluid filled with nanoparticles, due to the implementation of radiation and convective boundary condition. The flow is considered impinging obliquely in the region of oblique stagnation point on the stretching surface. The obtained governing partial differential equations are transformed into a system of ordinary differential equations by employing a suitable similarity transformation. The solution of the resulting equations is computed numerically using Chebyshev Spectral Newton Iterative Scheme (CSNIS). An excellent agreement with the results available in literature is obtained and shown through tables. The effects of involving parameters on the fluid flow and heat transfer are observed and shown through graphs. It is importantly noted that the larger values of Biot number imply the enhancement in heat transfer, thermal boundary layer thickness and concentration boundary layer thickness.
