Residence time distribution of solid particles in a continuous, high-aspect-ratio multiple-impeller stirred vessel

Residence Time Distribution and Flow Characteristic in a Multistage Stirred Reactor

“…Haug organized the data from his experiment and literatures in a six-stage stirrer reactor, 14 and it is found that the backmixing flow rate is a function of the ratio of the tip velocity of the impeller to the flow rate in the reactor, as well as a function of the baffle and the impeller configurations. Scargiali et al explored the fluid RTD in a three-stage stirrer reactor, 15 where the RTD result agreed well with the model of ideally mixed tanks with backflow. As long as the backflow rate was determined, the number of equivalent reactors of the multistage stirred reactor can be controlled.…”
