Delivery Rate of Axial Flow Impellers in Mixers with Wall-Mounted Baffles

The analytical relationship between the delivery-rate criterion of an axial flow impeller and the power criterion has been found using the angular momentum equation as a basis. This relationship was derived under the assumption of a constant field of tangential velocities along the height of a mixer. Based on the experimentally found velocity fields available in the literature, the equation for calculating the coefficient of proportionality between the delivery rate of a flow impeller and the circulation flow rate is obtained. The published experimental delivery rates and circulation flow rates of a flow impeller are compared with their calculated values found by the proposed equations.
