Type: article
Abstract: The influence of using nanoparticles with and without magnetic field on the characteristics of the flow and heat transfer rate is experimentally through a horizontal pipe. The base working fluid is distilled water, and the added nanoparticles are iron oxide (Fe3O4), with a volume fraction of (φ= 0.3, 0.6 and 0.9%). The intensity of the supplied magnetic field is (0.1 Tesla). The experiments are conducted at different heat fluxes (12.7, 15.9, 19.8 kW/m2), two different inlet temperatures (23, 45 oC), four different flow rates (2, 3, 3.5, 4, l/min) and range of Reynolds number (3930-7860). The results show that an increase in the concentration of nanofluids and heat flux give a boost in Nusselt number. Also, it is found that the use of a magnetic intensity enhances further heat transfer. The maximum enhancement in Nusselt number is about (18.3%) without using a magnetic field, and (20.1%) with the magnetic field, at a concentration of nanofluid of (φ = 0.9%) and lower heat flux
