Abstract

A survey of the current applications of large-eddy simulation in the prediction of noise from turbulent jets is given. After summarizing the numerical techniques used the data predicted by the simulations are given at conditions of subsonic, heated jets to supersonic, unheated jets. Mach numbers between 0.3 and 2.0 are considered. Following the data presentation an analysis of the trends exhibited by the data is given, with special attention paid to relationship between numerical and/or modeling choices and the prediction accuracy. The data supports the conclusion that the most limiting factor in current large-eddy simulations is the thickness of the initial shear layer, which is roughly one order-of-magnitude thicker than what is found experimentally. The influence of inflow forcing is also discussed in depth. A listing of some of the open questions and future directions concerning jet noise predictions using large-eddy simulation concludes the survey.
