Newtonian flow over a porous stretching/shrinking sheet with CNTS and heat transfer

The current work investigates the thermohydrodynamic attribution of boundary layer flow of an incompressible liquid with carbon nanotubes (CNTs) of two types, viz. SWCNTs and MWCNTs, considering the mass transpiration and radiation effect. Consequently, the employed CNTs are examined with promising prospective for the heat transfer applications. The quiescent nanofluid is exposed to a shear stress through the linear velocity of the shrinking porous sheet. On adopting suitable similarity transformation, the set of PDEs are converted into the set of nonlinear ODEs. Considering two types of boundary conditions for the temperature distribution like power-law wall temperature and heat flux. The closed-form analytical solutions are obtained for velocity and temperature in terms of Kummer's functions. The behavior of velocity distribution and wall heat flux is analyzed through the effect of shrinking sheet, porosity parameter, mass transpiration, Prandtl number.
