Investigation of a three-dimensional design procedure for axial flow pump impellers


Bowerman, Ray D. (1955) Investigation of a three-dimensional design procedure for axial flow pump impellers. Engineer's thesis, California Institute of Technology. doi:10.7907/HXHG-QJ10.


A design procedure for axial flow pump impellers is presented that accounts for induced interference effects in the prediction of performance. Induced interference velocities at an impeller blade have been calculated using a three-dimensional model that includes the effects of the other blades and of the total downstream vorticity along the centerline of the pump.

The design method considers improvement of cavitation conditions by specifying the radial variation of the design parameters such that the pressure distribuions on all radial sections are similar.

Experimental work on a two-bladed impeller has yielded results that give good support to all aspects of the design procedure.
