Prediction of far-field noise from installed corrugated nozzles

HIGHLIGHTS

  • What: Of particular interest in this paper is the model proposed by Lyu and Dowling , which has been shown to be accurate and robust. The aim of this study is to evaluate the reliability and robustness of Lyu and Dowling`s model when dealing with subtle geometric alterations at the nozzle exit, under both static and in-flight conditions. To initially evaluate the accuracy of Lyu and Dowling`s model, the authors examine the impact of the number of modes on the predictions of installed noise for nozzle SC12 (12 degrees penetration).
