Boundary layer flow and heat transfer analysis on Cu-water nanofluid flow over a stretching cylinder with slip

Abstract

Investigation of heat transfer effect on Cu-water nanofluid flow past a stretching cylinder is focused in the recent article. The numerical method of nonlinear known as RKF 4â5th has been taken into account along with shooting process to obtain the solution of required ODEs with supplementary boundary conditions. The influence of thermal radiation parameter on non-dimensional skin friction and Nusselt number along with convection parameter, solid particle volume fraction and heat generation/absorption parameter are represented in the tabular and graphical way. The volume fraction of nanofluid is considered as 0â6% with an increment of 2%. The thermal radiation parameter lies in the domain of [0.3,5]. Moreover, the values of porosity parameter (λ) and heat generation/absorption parameter (Q) are varied as 0.5⩽λ⩽2.5 and -2⩽Q⩽2, respectively. The data of authors declared that augmentation is perceived in temperature curves with the volume fraction of solid particles; moreover, momentum boundary layer depreciates with boost in volume fraction parameter of copper (Cu) particles. The obtained data are distinguished with earlier study and admirable agreement has been noted. Keywords: Heat generation/absorption, Nanofluid, Porous medium, Stretching cylinder, Thermal radiation
