Abstract
The linearized perturbed compressible equation (LPCE) proposed for various low Mach number aeroacoustic problems is reviewed. In this method, the acoustic field is predicted by acquiring the noise source, DP/Dt, from the hydrodynamic flow field computed by large-eddy simulation. We present theoretical backgrounds of LES/LPCE hybrid approach and its application to turbulent edge-scattering noise.
