Methods for Identifying Acoustic Emissions From the Front Face of a Small Piezoelectric Blower

Methods for Identifying Acoustic Emissions From the Front Face of a Small Piezoelectric Blower

This thesis focuses on identifying acoustic noise generating components in piezoelectric blowers through transverse velocity measurements and the development of a numerical fluid model. Piezoelectric ceramics have proven useful for many industries and areas of research involving: high precision actu...
