| Sumario: | In this paper, an experimental investigation on dynamic viscosity has been performed. Then, Experimental results were compared with classic theoretical models such as, Einstein and Wang models. The results represented that, the results obtained from experimental tests were far away from the theoretical models. Therefor an empirical correlation for predicting the effective dynamic viscosity of Alumina-water nanofluids has proposed and discussed. In this study, there was used from cone and plate Brookfield viscometer and the viscosities of Al2O3-water nanofluids with different solid volume fractions of 0. 05 (5. 0%), 0. 4(4. 0%), 0. 03 (3. 0%), 0. 02(2. 0%), 0. 01 (1. 0%), 0. 005 (0. 5%) and 0. 0025 (0. 25%) is measured at room temperature. |
