title: Acoustic waves in thin-walled elastic tube with polymeric solution
abstract: Acoustic waves in a pipe with polymeric liquid are investigated within a quasi-one-dimensional approach. Analysis of the dispersion equation has shown that rheological features lead to essential changes in both attenuation and speed of the sound. The results may find application in acoustic rheometry of polymeric liquids and for modeling of fast dynamic processes in polymer production technology.
