초록정보

Flow characteristics of the highly concentrated (50~60wt.%) CWM(Coal-Water Mixture) flowing in a 1-inch horizontal pipe was investigated. Rheological behavior of the CWM could be measured using rotational viscometer and the data obtained were fitted to the power law model. Consistency, K and yield stress increased with the solid concentration and the mean particle size. Increasing the temperature had no great effect on the yield stress and the flow behavior index, n, but consistency was decreased. By using a selected additive for improving the fluidity, apparent viscosity was reduced drastically. In our slurry flow experiments, we measured the flow rate and the pressure drop through straight sections of the test pipe with the inverted type manometer. The pressure drop correlation based upon power law model constant was compared with the experimental data for various CWM. Also $f-N^{\ast}_{Re}$ correlation was derived from the Metzner and Reed generalized Reynolds number.
