An analytical calculation method of 3 base fluids suspend by CNTs hybrid
nanoparticle over a vertical circular cylinder with sinusoidal radius
Abstract
In this research, the specification of 3-dimensional flow stagnation
point of hybrid Nano fluids passing through circular cylinder with
sinusoidal radius are analyzed. C2H6O2, H2O and Engine oil are used as
an ordinary liquid, while nano-particles include SWCNT and MWCNT. Fluid
stream is taken into account with/without considering the effect of
thermal slippage. Higher order non-linear phrases are transformed to
ordinary prime-order differential equations and then solved applying the
Analytical Method (HPM) in Matlab-14 software. Graphical analysis of the
impressive parameters like: Prandtl number, thermal slip parameter, CNTs
volume fraction is precisely checked on the profiles of velocity and
temperature for various carbon nano-tubes. Consequences display that:
cooling process or heat transfer rate can be increased by employing
smaller thermal slippage parameter. Further, due to the better thermal
conductivity of SWCNT carbon nanotube, the temperature increase in these
carbon nanotubes is more than that of MWCNT.
