RISA Simple Configuration of an Actively Synthesized Gyroscopic-Nonreciprocal Acoustic Metamaterial
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple configuration of an active nonreciprocal gyroscopic metamaterial (NGMM) is presented. In the proposed NGMM system, a one-dimensional acoustic cavity is provided with piezoelectric boundaries acting as a collocated ...
New Methodology for the Identification of the Leakage Paths and Guidelines for the Design of Common Rail Injectors With Reduced Leakage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The static leakage of a common rail (CR) injector is the flow-rate that is recirculated from the injector when the pilot-stage is not actuated. It is a critical issue in the development of modern CR injectors, because it ...
