Numerical study for slip flow of carbon–water nanofluids

Abstract

Three-dimensional flow of carbon–water nanofluid due to slendering nonlinear stretching sheet with slip effects is covered in this study. Nanofluid saturates the porous space. We consider water based SWNT and MWCNT nanofluids in this study. Isothermal model of homogeneous–heterogeneous reactions regulates the concentration. The system of partial differential equations is converted into ordinary differential equations. The numerical solutions are obtained through bvp4c technique. Tabulated values and graphical illustrations are pointed out for the influence of sundry variables. Volume fraction corresponds to enhancing the flow behavior while slip variable shows decline in flow. The simulations show that wall heat flux is inversely proportional to slip effect. However value of heat flux is predicted more in case of larger values of variable thickness variable. Heat transfer performance of MCNT case is higher when compared with SWCNT. Homogeneous variable and Schmidt number have opposite behaviors on nanoparticle concentration distribution. Favorable agreement is shown through comparison of past and present results in limiting case.
