Abstract
A mixer assembly comprises a motor, a motor shaft, a propeller connected to the motor shaft and in operation driven by the motor in a first direction of rotation about a propeller axis, the propeller fully submersed in liquid during operation and in rotation generating liquid flow from a suction side to a pressure side of the propeller. Flow control vanes are arranged on the suction side of the propeller, and oriented in an axial plane to deflect the liquid from substantially axial flow into a flow containing a circumferential component of direction which is opposed to the direction of rotation of the propeller. A method for providing axial liquid flow from a mixer propeller that is fully submerged in liquid during operation comprises the steps of applying flow control on the suction side of the mixer propeller through the arrangement of flow control vanes.
