A CFD Study of [C2mim][CH3SO3]/Al 2 O 3 Ionanofluid Flow and Heat Transfer in Grooved Tubes

摘要: The present article deals with the computational fluid dynamics (CFD) investigation of flow and heat transfer a [C2mim][CH3SO3]/Al2O3 ionanofluid in one conventional tube two different grooved tubes. is considered to be single-phase laminar (500 < Re < 2000), range nanoparticle concentration between 0.05 2 %. For properties ionanofluid, experimental data available literature have been used. results relative coefficient, pumping power, field synergy are presented for three tubes at various Reynolds numbers concentrations. It found that effect grooves more pronounced low Moreover, coefficient power rise by increasing concentration. Adding nanoparticles has greater impact on lower numbers. intensified Re increment. More uniform temperature velocity distributions achieved because severe mixing induced grooves. Both greatest highest occur having spirally corrugated show varies changing geometry. At volume % Re = 500, increases by 15.54 compared tube.
