Numerical investigation of zeros of some dispersion relations appearing in sound attenuation problems in a circular lined duct
In this paper the zeros of some dispersion relations apperaring in sound attenuation problems in circular lined ducts, carrying a gas flow, are investigated numerically. To find the values of frequencies for which the dispersion relations vanish is not easy at all. That is beacause these relations c...
