Three dimensional Darcy-Forchheimer radiated flow of single and multiwall carbon nanotubes over a rotating stretchable disk with convective heat generation and absorption

Several important characteristics of CNTs (carbon nanotubes) like excellent electrical conductivities, extraordinary thermal conductivities, good mechanical and chemical stability and extremely light mass make CNTs a model material which is utilized in various electro-chemical mechanisms. Keeping the said significance of carbon nanotubes in notice our main aim in this analysis is to establish the import relation of Darcy Forchheimer in three dimensional (3D) flows of classical fluid (water) based CNTs in presence of slip velocity due to rotating stretchable disk. Analysis of nanoparticles like single and multi-walled (SWCNTs, MWCNTs) carbon nanotubes are developed and equated. Present investigation further comprises non-linear thermal radiation, heat generation/absorption as well as convective thermal boundary condition aspects. The pertinent non-linear ordinary differential equations after utilizing the appropriate variables are calculated. HAM (Homotopy Analysis Method) technique is utilized for the analysis of velocities and thermal distribution. Various graphs have been plotted in order to examine that by what means the velocities and thermal field are altered by different model quantities. The main features of flow like the CFReα, CGReα (skin friction), Nu(Reα)−1/2 (heat transfer rate) have been intended numerically and graphically.
