About this document
Aanonsen Distortion Harmonic Generation Nearfield Finite Amplitude Sound Beam by ryanharne is a document available to read on EtoBox.
This paper investigates distortion and harmonic generation in the nearfield of a finite amplitude sound beam in an absorbing fluid. The authors derive a solution using a Fourier series expansion for sound pressure and analyze the effects of different source conditions, including uniformly excited circular pistons and Gaussian distributions. The results indicate that significant nearfield effects propagate beyond the Rayleigh distance, and the findings are compared with previous models and numerical results.
