| Abstract: | Based on simplified Donnel shell theory and acoustic wave propagation equation in a pipe with fully developed turbulent flow, free vibration equations of fluid flowing piping system were derived. Types of wave corresponding to various circumference mode ( n =0, 1, 2, 5) and various axial wavenumber were analyzed in details. The fundamental types of wave were determined which were responsible for vibration energy transmission in pipe. Being essential and necessary to calculate energy distribution and determine energy measurement scheme dispersion curves were supplied. |
