Abstract
The acoustic characteristics of twin jet screech tone is studied for various jet configurations such as both square and diamond. The measurement is carried out along the jet direction for various angles at two different planes using a microphone and the jet flow visualization is done by the shadowgraph technique. It is observed that the screech tone suppression is taken place for diamond jet configuration for the small jet spacing S = 0.5. By comparing the directivity pattern of twin jets with single jet, it is found that the twin jet behave as a single jet at higher nozzle pressure ratio. Copyright ©2010 by ASME.
