This research is to explore the stagnation point flow problem in carbon nanotubes
(CNTs) with suction/injection impacts over a stretching/shrinking sheet. Nonlinear
ordinary differential equations systems are transformed from the governing partial
differential equations by applying similarity transformation, thus resolved numerically
using a bvp4c solver in MATLAB. Two types of CNTs are used which are SWCNTs (single
walled) and MWCNTs (multi-walled) and water as the base fluids. Influence of the
velocity, temperature, skin friction and Nusselt numbers are studied and displayed in
the graphs form. It is concluded that the suction effect could widen the range of
solutions exist and the effect of injection acted on the contrary. Also, the solutions are
dual for shrinking sheet while unique for stretching sheet.
