Acoustic Radiation and Training for Electroacoustic Transducers
Abstract
The analytical treatment of radiation for many types of transducers are not well known or characterized andsimplified approximation"s used and often difficult to implement. For example, the problem of acousticradiation in flextensional transducers, slotted cylind"ers and short extensional mode cylinders do not haveanalytical solutions and must be solved numerically. This effort will study complex acoustic radiation (resistiveand reactive components) and organize these results in one summary document. Combining this informationusing the energy method offers a powerful tool for modeling transducers and excellent opportunity to trainundergraduate and/or graduate students interested in acoustic transduction. The transduction problem requiresadequate description of the radiation im"pedance. We intend on solving the problems for many transducer types including short cylinders, baffled elements, vibrating pistons"" with and without baffles, flextensional transducers and slotted cylinders. A major effort of the proposal will also train student i""nterns, undergraduates and/or graduate students with training and collaboration at NUWC in Newport. Summary presentations, lectures" and training will be provided for ONR/NUWC.
