Abstract
Experiments were conducted using three different approaches to investigate the possibility of jet-installation noise reduction. The experiments were carried out for cold jets with round nozzle for Mach numbers ranging from 0.3 to 0.9. The three approaches for jet-installation noise reduction trough surface treatments were investigated. It involved the application of various types of trailing-edge modifications such as porous, serrated, and finlet to the trailing-edge of the flat-plate placed at the proximity to the jet. The characteristics of the jet hydrodynamic pressure fluctuations were investigated in the axial direction using far-field measurements. The trailing edge treatments were investigated for five different flat-plate positions away from the jet axis for a wide range of Mach numbers. This experimental study on jet-installation noise will aid us to explore the relationships between the trailing-edge treatments, plate distance, and far-field acoustics.
