| Abstract: | Experiments have beed performed to investigate the power consumption that three shaft agitators, namely the anchor, the propeller, and the tooth-blade were employed under the various Reynolds number in Newtonian liquid. The Reynolds number range is tested between 0. 8 and 300 000. The liquid viscosity is 0. 001 to 84 Pa. s. The experiment process was controlled by computer. The strain gauge technique was used to measure the power input. The influence among the different impellers have been tested. Power correlations of each impeller at various conditions are presented. Marquardt-method was used to determine the model parameters. |
