The extraordinary characteristics of carbon nanotubes like good electrical conductivity, high thermal conductivity, chemical and mechanical stability, physicochemical compatibility and light weight make them an ideal material to be utilized in electrochemical devices. Having such importance of carbon nanotubes in mind our objective in this research is to describe the significance of Darcy–Forchheimer relation in water-based carbon nanotubes (CNTs) flow subject to a rotating disk. Analysis for single and multi walled carbon nanotubes (SWCNTs, MWCNTs) is acquired and compared. The current research further comprises slip (velocity, thermal) and heat generation aspects. Relevant ordinary differential systems after utilizing proper transformations are computed. Shooting scheme is utilized for the analysis. Temperature, skin friction, velocity and Nusselt number have been addressed. The described analysis reveals similar impacts of velocity and thermal slip variables against velocities and temperature fields. Furthermore temperature distribution and rate of heat transfer are enhanced for higher estimation of radiation parameter. •Darcy–Forchheimer flow due to a rotating disk is considered.•Effect of carbon nanotubes in water-based liquid is addressed.•Heat transfer captures thermal radiation and heat generation/absorption aspects.•The results are plotted and interpreted.•Shooting scheme is utilized for the computation of nonlinear systems.
