摘要：

Non-Newtonian fluids play an important role in the chemical engineering industry. In this paper, the effect of adding TiO2, Al2O(3), and CuO nanoparticles on the convective heat transfer coefficient of a Herschel-Bulkley fluid is investigated. A local and average heat transfer coefficient of the base fluid and nanoparticle suspension is calculated. Experimental data shows that the adding different concentrations of TiO2, Al2O(3) and CuO increase these parameters. Also it is observed that though nanoparticles increase the thermal conductivity of a base fluid, the change of its rheological property has a greater effect on increasing heat transfer coefficient.
