| Özet |
| The main aim of the study is to investigate the impact of wavy tape geometry and magnetic nanofluid on thermal and hydraulic characteristic under a laminar flow regime. In this direction, it was examined numerically for convection heat transfer and flow behaviors of CoFe2O4/H2O flowing with 1% volume fraction in a circular channel with different wavy tape forms. This work has conducted the analyses for fully developed flow under uniform and constant heat f lux conditions of 2000 W/m2. The analyzes have been implemented with Reynolds numbers ranging from 500 to 2000. All analysis have been carried out using laminar model and single-phase approach. Finally, heat transfer ratio and Darcy friction factor was gained for the tube with wavy tape amplitude of wave ratio (y=h/w) of 4. On the other hand, it was observed that average Nusselt number and Darcy friction factor values are suitable with the literature. The best heat transfer performance value was achieved at Re=2000. Besides, it was obtained that the Darcy friction factor decreased with increasing Reynolds number, while maximum total entropy generation was reached for CoFe2O4/H2O flow having 1% volume fraction in tube with wavy tape. |
