Description
Summary:The study of rotating flow with nanoparticles over multiple geometries under substantial physical implications has frequent applications in engineering and manufacturing fields. The aim and novelty in this analysis focus on the nanofluid flow with heat transfer for single-wall carbon nanotube (SWCNT) and multi-wall carbon nanotube (MWCNT) due to the stretching and torsional motion of a cylinder. The static (Xue) and dynamic (Buongiorno) models are executed to reveal the heat and mass transfers features. Further, the characteristics of viscous dissipation, thermal radiation and magnetic field are considered in the present physical model. The motion equations are transformed into a system of non-linear ODEs by appropriate similarity transformations. Equations solved numerically by built-in technique bvp4c in MATLAB. The computation outcomes show that the effects of Reynolds number, magnetic field parameter, radiation parameter, Prandtl number, Eckert number and volume fraction of nanoparticles are efficient on flow field. Velocity and temperature fields are identified in a diminishing behavior by the enhancement of Reynolds number. Further, the effects of Lorentz force causes to decrease the velocity field while increases the temperature field. It is observed that MWCNT makes a great contribution in augmenting the heat transfer rate compared to SWCNT nanoparticles.
