ABSTRAKT

A novel acoustic analogy approach is considered for jet noise modeling within the generalized acoustic analogy framework. The approach is based on large eddy simulation and is empirical-parameter free. Numerical predictions are provided for a subsonic isothermal axisymmetric jet case (JEAN ex- periment).
