Aeroacoustics sits at the intersection of fluid dynamics and acoustics, investigating how turbulent and unsteady flows generate sound. Pioneered by Sir James Lighthill in 1952, the field explains why jet engines roar, why wind whistles past wires, and why supersonic aircraft produce thunderous sonic booms. Lighthill's acoustic analogy reformulated the Navier-Stokes equations into an inhomogeneous wave equation, revealing that aerodynamic sound scales with extreme powers of flow velocity.
These simulations let you explore the fundamental mechanisms of flow-generated noise: turbulent jet mixing, boundary layer pressure fluctuations, rotor tonal and broadband radiation, vortex-shedding aeolian tones, and shock wave propagation. Adjust flow parameters and watch how noise spectra, directivity patterns, and pressure fields respond in real time.
