Abstract
This paper investigates convection flow of SWCNT and MWCNT nanotubes with base fluid ethylene glycol (C2H6O2) over a stretching porous surface. The Porous medium is described by Darcy's law. Thermal radiation and heat generation are considered in the energy equation. Using the above assumptions, a system of partial differential equation (PDEs) governs the flow problem. Dimensionless variables are introduced to transform and make the PDEs dimensionless. Finite difference scheme is utilized to solve these PDEs. Impact of different flow parameters on velocity, temperature, Nusselt number and skin friction are displayed graphically. The obtained results describe that the velocity enhances for higher Reynolds number while declines for porosity parameter and nanotubes concentration. Temperature is the increasing function for higher value of heat generation absorption coefficient.
