Sound radiated from low Mach number turbulent boundary layer flows(Turbulent boundary layer on a smooth plate and over a small forward facing step)
Published 2021-01-01“…High-resolution numerical simulation has been performed to study aeroacoustic noise radiated from a turbulent boundary layer at freestream Mach number Ma = 0.3, which develops on a smooth flat plate and over a small forward-facing step. Sound waves radiated from the turbulent boundary layer on the flat plate are dominant in a very-low-frequency band and have characteristics of a linear sound source. …”
