摘要：

In this article, thermal and hydrodynamic performances of a miniature tangential heat sink are investigated experimentally by using Al2O3-H2O and TiO2-H2O nanofluids. The effects of flow rate and volume concentration on the thermal performance have been investigated for the Reynolds number range of 210 to 1,100. Experimental results show that the average convective heat transfer coefficient increases 14 and 11% and the bottom temperature of the heat sink decreases 2.2 degrees C and 1.6 degrees C by using Al2O3-H2O and TiO2-H2O nanofluid instead of pure distilled water, respectively.
