Embodiments of the invention provide a method, device, and turbopump configured to suppress higher order cavitations at an inducer tip in a turbopump. An inducer having a tip is rotated, and a first flow is induced axially through the inducer at a first velocity. A second fluid flow is introduced toward a tip of the inducer substantially parallel to the first fluid flow at a second velocity that is greater than the first velocity, such that back flow through the tip of the inducer is reduced.
What is claimed is: 1. A method for suppressing cavitation at an inducer blade tip in a pump, the method comprising: rotating an inducer having a tip clearance; inducing a first fluid flow axially through the inducer at a first velocity; and introducing a second fluid flow toward the tip clearance substantially parallel to the first fluid flow at a flow rate with a second velocity, greater than the first velocity, such that back flow through the tip clearance of the inducer is reduced, wherein introducing the second fluid flow includes introducing the s...
