CNTs-Nanofluid flow in a Rotating system between the gap of a disk and cone

Abstract

In the current article, the focus of the study is the rate of heat transfer in three-dimensional coordinates. The cone-disk apparatus is assumed with rotating disk and stationary cone or may be taken with a stationary disk and rotating cone, or both of them co-rotating, or counter-rotating, along single-wall carbon nanotubes (SWCNTs) and multiple wall carbon nanotubes (MWCNTs) of water-based. By the definition of well-known thermal physical possessions of CNTs heat transfer enhancement at both the cone-disk surfaces is investigated. Further magnetism (MHD) is enforced perpendicular to the flow of nanofluid between the cone and the disk surface. The conical gap section is considered moderate for the better result of heat transfer. The modeled equations for the nonlinear problem are solved through an analytical approach Homotopy analysis method (HAM). On behalf of graphical outcomes of velocity, concentration, and temperature profiles the HAM BVPh 2.0 package has been used. Moreover numerical values of skin friction, Nusselt number are calculated through the effect of SWCNTs and MWCNTs at both the cone and disk surface with a moderate apex angle. On behalf of the concentration equation, the Sherwood number is also deliberate in the present analysis.
