Abstract: In an effort to enhance heat transfer in the laminar flow regime of a heating duct, TiO2 and SiO2 nanoparticles were added to water to create nanofluids with a higher thermal conductivity than that of the water alone. Twist-tape was also used to enhance heat transfer within the duct. The thermal conductivities of the nanofluids were measured using the Hot Disk Transient Plane Source 2500S instrument. It was found that the use of twist tape alone gave a significant enhancement of convective heat transfer in the laminar flow, but that the use of nanofluids further enhanced the heat transfer.
