The combined effects of slip and convective boundary conditions on stagnation-point flow of CNT suspended nanofluid over a stretching sheet

Abstract

In this article, we discussed the two dimensional stagnation-point flow of carbon nanotubes towards a stretching sheet with water as the base fluid under the influence of slip effects and convective boundary condition using a homogeneous model. Similarity transformations are used to simplify the governing boundary layer equations of nanofluid. This is the first article on the stagnation point flow of CNTs over a stretching sheet. Two types of CNTs, single- and multi-wall CNTs are used with water as the base fluid. The resulting nonlinear coupled equations with the relevant boundary conditions are solved numerically using the shooting method. The influence of the flow parameters on the dimensionless velocity, temperature, skin friction, and Nusselt numbers is explored and presented in the form of graphs and interpreted physically. © 2014 Elsevier B.V.
