Acoustic compressor coupled with fluidic diodes

Performance of a fluidic diode coupled with an acoustic compressor is studied. Fluidic diodes are arranged in series to improve the rectification. Experiments were done in configurations of 1, 2, 3 and 4 diodes in series. The volume flow and pressure measurements are presented. Better rectification is achieved by arranging the diodes in series. Also it was found that fluidic diodes worked at operating frequencies of the order 900Hz. © 2013 Acoustical Society of America.
