Název v původním jazyce

Axial force at the vessel bottom induced by axial impellers

Popis výsledku v původním jazyce

This paper deals with a study of axial force affecting the flat bottom of cylindrical stirred vessel. The vessel is equipped with four radial baffles and is stirred with a four 45o pitched blade impeller pumping downwards. The set of pressure transducersis located along the whole radius of the flat bottom between two radial baffles. Radial distribution of the dynamic pressures indicated by the transducers is measured in dependence of impeller off-bottom clearance and impeller speed. It follows from results of experiments made that under turbulent regime of flow of agitated liquid the mean time values of the dynamic pressures affecting the bottom do not depend on the impeller speed but depend on the impeller off-bottom clearance. According to the modelof the flow pattern of agitated liquid along the flat bottom of mixing vessel with pitched blade impeller three subregions can be considered in this region: the liquid jet streaming downwards from the impeller deviates from its vertical
