Abstract

The present study deals with the design, development, and fabrication of a nozzle with flowconditioning assembly and using it to study jet flow acoustics. The flow is conditioned by severalmeans before the nozzle exits and the conditioned flow is allowed to exit the nozzle as jet. Thisconditioned jet flow produces aerodynamically generated noise and the same is measured using amicrophone. The microphone is placed perpendicular to the jet axis and the measurements arerecorded for various regimes. The results will be discussed based on the acoustic spectra and thejet decay characteristics.
