Abstract
The objective of this article is to investigate the stagnation point flow with variable heat flux. Flow is caused by a linear stretched surface. The velocity and thermal fields of this study strongly depend upon the shape and the needle size. Water-carbon nanofluid in presence of thin needle is considered. Non-linear ordinary differential equations are obtained by using suitable transformation through fundamental laws of mass, momentum and energy. ND Solve shooting technique is used for solving differential equations numerically. The effects of physical parameters on velocity and temperature profiles are pointed out. It is observed that velocity profile enhances for larger values of nanoparticles volume fraction. (C) 2016 Elsevier B.V. All rights reserved.
