ABSTRACTABSTRACT
Design and development of a high speed Design and development of a high speed and precision magnetostrictive fluid pumpand precision magnetostrictive fluid pump
Design a pump operating at up to 10,000 Design a pump operating at up to 10,000 Hz that functions using magnetostrictive Hz that functions using magnetostrictive properties of terfenol-d. properties of terfenol-d.
Large volumes are enabled by the high Large volumes are enabled by the high frequency displacement frequency displacement
