Nonaxisymmetric wave propagation through a viscous fluid in a viscoelastic tube

The eigensolution of a nonaxisymmetric linear wave propagation through a viscous fluid in a viscoelastic pipe is obtained. The solution can serve as a foundation for studying nonaxisymmetric blood flow. Some leading eigenvalues for two special cases are computed. The result shows that nonaxisymmetri...

Description
Summary:The eigensolution of a nonaxisymmetric linear wave propagation through a viscous fluid in a viscoelastic pipe is obtained. The solution can serve as a foundation for studying nonaxisymmetric blood flow. Some leading eigenvalues for two special cases are computed. The result shows that nonaxisymmetric modes decay fast during their propagation.
