| dc.description.abstract | This research presents the results of a numerical study of forced convection in adiabatic square ventilated enclosure containing a hot hexagonal cylinder rotating around its axis. The direction of the forced flow of Water-copper cooling nanofluid is perpendicular to the axis of the cylinder. The governing equations of the flow for an incompressible Newtonian nanofluid are assumed to be two-dimensional, steady and laminar. The finite volume method is used for numerical simulations. A series of calculations are carried out to study the effects of the main influencing factors; Reynolds numbers (200≤Re≤1000), rotational Reynolds numbers(-30≤Reω≤30), nanoparticle volume fractions (0≤∅≤3%) and hexagonal cylinder rotation direction on the heat transfer enhancement. The results show that the increase in the entry speed of the nanofluid into the cavity as well as the increase in the hexagonal cylinder’s angular velocity increases the heat transfer between the hot hexagonal cylinder’s and the cold nanofluid. The increase in the nanoparticles volume fraction only increases the heat exchange rate in the cavity when the inlet velocity reaches the value corresponding to a Re number equal to 1000. | |
