Abstract: A detailed development of a local heat transfer probe specifically designed for analyzing nanofluids. In this paper iron oxide is used as a test subject to determine the accuracy of the probe. Different concentrations were measured ranging between 0 and 0.09% by volume. Thermal conductivity is also measured by a TLS-100 instrument, based on the transient line source. It is shown that the heat flow coefficient increases with the addition of nanoparticles. There was also a noticeable increase in the Reynolds Nusselt number, as well as the particle concentration.
