Darcy-Forchheimer flow of carbon nanotubes subject to heat flux boundary condition

Flow of water-based carbon nanotubes past an exponentially stretching curved surface is modeled. Analysis is carried out for imposed flux condition and heat generation/absorption. Darcy-Forchheimer expression is used to characterize the flow in porous space. Carbon nanotubes of two types (recognized as SWCNT and MWCNT) are utilized. Adequate transformations correspond to system of coupled differential equations. The resulting nonlinear system is solved by NDSolve technique. Influences of various pertinent variables for quantities of interest are examined. Our results reveal that temperature against volume fraction of nanoparticles is enhanced. (C) 2019 Elsevier B.V.
