Gas-liquid dispersion agitated by closed turbine type impeller
Gas-liquid agitation by a turbine-type impeller having shrouds structurally (closed disk turbine impeller, CDT) was studied by examination of the flow behavior of the gas-liquid mixture in the impeller region, with energy consideration based on the impeller power characteristics in the gassed liquid...

| description | Gas-liquid agitation by a turbine-type impeller having shrouds structurally (closed disk turbine impeller, CDT) was studied by examination of the flow behavior of the gas-liquid mixture in the impeller region, with energy consideration based on the impeller power characteristics in the gassed liquid. The way in formation of the gas cavities and dispersion as the gas bubbles using the CDT differed from that using a conventional disk turbine impeller (open impeller, ODT). The difference in relative power consumption, i.e., the ratio of gassed to ungassed power consumption, between the CDT and ODT was related to the configurations of the gas cavities. |
