Effects of Suction/Injection on Stagnation Point Flow over a Nonlinearly Stretching/Shrinking Sheet in a Carbon Nanotubes

Abstract

This research will explore the issue of stagnation point flow in carbon nanotubes with suction/injection impacts by a nonlinear stretching/shrinking sheet. By practising a similarity transformation, the governing partial differential equations (PDEs) are converted to a scheme of nonlinear ordinary differential equations (ODEs). Then, settled numerically with applying a bvp4c solver in Matlab. Two types of carbon nanotubes (CNTs) are used which are SWCNTs (single-walled) and MWCNTs (multi?walled) and the base fluid used is water. In the form of graphs, the impact of the velocity, temperature, skin friction and numbers of Nusselts parameter is researched and displayed and interpreted physically. It is found that if only suction rises, the range of solutions will increase.
