Oblique Stagnation Point Flow of Carbon Nano Tube Based Fluid Over a Convective Surface

This article looks for 2-D oblique stagnation point flow of CNTs based fluid over a stretching convective surface. Cautious analysis is performed using water and engine oil based fluid with single and multi-wall CNTs. The governing partial differential equations along with their appropriate boundary conditions are transformed into coupled non-linear ordinary differential equations using suitable similarity transformations. An effective and robust numerical scheme is applied to solve these equations. Effect of significant physical parameters on the dimensionless velocity and temperature profiles are revealed through graphs. Physical quantities such as local Skin frictions co-efficient and heat flux are tabulated. Engine oil based fluid proved more promising than water based fluid for single as well as multi-wall CNTs in terms of heat transfer rate. Computed numerical results of the present analysis are found to be in visible agreement with the existing literature for the limiting case, which makes us confident that ours calculated results are very much correct.
