A FORTRAN Computer Program for Calculating the Propagation of Plane, Cylindrical, or Spherical Finite Amplitude Waves

Abstract

A numerical solution to the generalized Burgers' radial wave equation has been developed; it allows one to calculate stepwise the harmonic content of a finite amplitude wave in the frequency domain for the case of plane, cylindrical, or spherical geometry. The finite amplitude wave may have any initial harmonic content with arbitrary phase, and the absorption coefficient of each harmonic is independently adjustable. Remaining in the frequency domain allows a much larger step than conventional algorithms, which alternate between the time and frequency domains. A listing of the computer program is included.
