Abstract

This study aims to investigate the attenuation and dispersion of pressure waves propagating in aerosols. A numerical scheme based on Crank-Nicolson finite differencing and trapezoidal quadrature discretization methods is employed to simulate the evolutions of several pressure waves with different initial profiles (disturbances). The attenuation and dispersion are observed from the spectra of the wave profiles at different times of propagation obtained by performing FFT (Fast Fourier Transform) to the simulated wave profiles. Simulation results show distinctive behaviors of different pressure disturbances propagating through the same medium.
