Acoustic Modeling Using the Aeroacoustic Wave Equation Based on Pierce’s Operator

What is it about?

We investigated for the first time the capabilities of an aeroacoustic wave equation based on Pierce's operator (AWE-PO) for modeling flow-induced sound and for sound prediction. The computations using AWE-PO are found to provide acoustic intensities within 1.8dB from a reference direct numerical simulation for an isothermal two-dimensional mixing layer application.
