Stirred vessels are used in the process industries for a variety of applications. Multiple-impeller stirred tank is widely used in process such as gas-liquid dispersion, high viscous fluid mixing. So the hydrodynamics of the flow is very important for designing and optimization. Most researches of multiple-impeller are focused on the radial impeller, and reports about axial impeller are very few.
