Abstracts:

This paper describes an experimental study of the heat transfer nanofluids in a cylindrical channel under constant heat flux density on the walls. The range of Reynolds numbers is from 100 to 2000 for laminar heat transfer and from 3000 to 10000 for turbulent heat transfer. A base fluid is distilled water. Nanoparticles are oxide powders of aluminum, silicon, copper and titanium. The diameter of the nanoparticles varies from 25 to 100 nm. Bulk concentration of nanoparticles varies from 0 to 2 volume percent. Outcomes of experiment are measure the average and local value of heat transfer coefficient at the channel walls and the pressure drop at the inlet and outlet of the channel.
