Numerical study of 3D rotating hybrid SWCNT–MWCNT flow over a convectively heated stretching surface with heat generation/absorption

Abstract

In the near future, the capability to improve the rate of heat transfer will increase due to the potential advantages and highly desired thermal properties of a new class of nanofluid called hybrid nanofluid. Hybrid nanofluid has been hypothesized as a potential cooling fluid. In particular, the present phenomenon concerns the study of the flow and heat transfer of rotating hybrid nanofluid in two directions over a convectively heated stretching surface. The impact of heat generation/absorption is also considered. Hybrid nanofluid made up of carbon nanotubes with convective boundary conditions is introduced for the first time and has not been investigated up until now. Numerical solutions of the complex problem are made using the bvp4c technique. A comparison between nanofluid and hybrid nanofluid is provided for the velocity in both directions and the temperature distributions as well as the reduced skin friction coefficient in both directions and the local Nusselt number. From the present analysis, it can be clearly observed that hybrid nanofluid consisting of carbon nanotubes gives a more preferable skin friction coefficient and rate of heat transfer than simple nanofluid.
