Power and Discharge Numbers of Radial-Flow Impellers - Fluid-Dynamic Interactions Between Impeller and Baffles
A physical model for the flow in a vessel equipped with radial-flow impellers and baffles is presented. It is based on the fluid-dynamic interaction between impeller and baffle, i.e. basically the transport of angular momentum from the stirrer to the baffle. By employing some integral notions, it is possible to calculate power and discharge numbers in stirred vessels from the geometry of the impeller and baffles in the vessel.
