| Abstract Scope |
Current experimental studies estimate convective heat transfer coefficients by applying an energy balance across the test section, measuring the supplied heat flux, nanofluid and surface temperatures, and the nanofluid's physical properties using primitive techniques. Most of the experimental research has focused on enhancing the heat transfer coefficient using metal oxide nanoparticles. The thermal conductivity and local heat transfer coefficient increased with increasing Fe2O3/water nanofluid volume fraction and temperature. Also, decreasing nanoparticle size enhanced both thermal conductivity and the local heat transfer coefficient. The results indicate that when the nanoparticle sizes become very small, the effect of such a small size on the heat transfer coefficients would be relatively larger than that of the larger size nanoparticles. |
