Oblique stagnation point flow of a non-Newtonian nanofluid over stretching surface with radiation: A numerical study

Abstract

In this study, we discussed the enhancement of thermal conductivity of elasticoviscous 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 transformation. The solution of the resulting equations is computed numerically using Chebyshev spectral newton iterative scheme. 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.

Analysis of Chemical Reaction on MHD Micropolar Fluid Flow over a Shrinking Sheet near Stagnation Point with Nanoparticles and External Heat

“…Haq et al [10] investigated MHD stagnation point flow with thermal radiation where he explored the zero normal flux condition near the wall of the sheet. Ghaffari et al [11] adopted the numerical Chebyshev Spectral Newton iterative scheme to study the flow behaviour of viscoelastic fluid over a stretching surface with oblique stagnation point considering radiation.…”

MHD slip flow of upper-convected Maxwell nanofluid over a stretching sheet with chemical reaction

“…Similarly, Mageswari and Nirmala [24] scrutinized stagnation point flow on stretching sheet with Newtonian heating. Moreover, Abuzar et al [25] have examined the effect of radiation and convective boundary condition on oblique stagnation point of non-Newtonian nanofluids over the stretching surface. Furthermore, stagnation point flow of nanofluid due to inclined stretching sheet was studied numerically by Yasin Abdela et al [26].…”
