The acoustic field generated by two coaxial jets is studied numerically. The turbulent non-isothermal flow is handled by Large Eddy Simulations (LES) and the acoustical perturbations are treated by solving an inhomogeneous wave equation. The acoustical source is obtained from the instantaneous LES flow field. The computed flow and acoustical fields are compared to measured data. Good agreement between the computed and the measured results has been found.
