The objective is to explore the role of anisotropy on aerodynamic mixing noise because of fine-scale turbulence. The usual assumption of isotropic turbulence is replaced with that of axisymmetric turbulence. The analysis is based on source terms of Lilley's equation. In addition, flowlacoustic interaction is accounted for in terms of a high-frequency solution to the axisymmetric Lilley's equation. In the limiting case of isotropy, various source correlation terms derived here simplify to those obtained with an isotropic turbulence model of Batchelor. A Reynolds-averaged Navier-Stokes solution with a k-∈ turbulence model for a Mach 1.0 jet is used to make flow and acoustic predictions. A parametric study of the turbulence scales indicates that anisotropy increases the peak noise level.
