Cavitation in Axial Flow Pumps: Termination Report [PDF]
, 1956 A series of cavitation experiments in an axial flow pump are described. It is found that cavitation first occurs in a tip vortex formed by the flow through the tip clearance space of the rotor blade.

Current Tracking Adaptive Control of Brushless DC Motors
International Journal of Adaptive Control and Signal Processing, EarlyView.In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Interaction of impeller and guide vane in a series-designed axial-flow pump [PDF]
, 2014 Axial-flow pumps or propeller pumps allow fluid to enter the impeller axially. The impeller can be driven directly by a sealed motor in the pipe or mounted to the pipe from the outside, or by a right angle drive shaft that pierces the pipe.
