WebSep 1, 1999 · This is the dispersion (characteristic) equation for circumferential waves in a layered cylinder. For each given k̄, the dispersion Eq. (20) may have many roots for ω ̄. As a result, the solution to Eq. (20) represents a family of curves, called modes. Each of these curves corresponds to a wave that propagates in the circumferential direction. WebFeb 1, 2024 · Axial and circumferential guided waves can be generated in cylindrical structures. The axially propagating waves are implemented to inspect long-range pipelines, and in most cases, axial waves are suitable to inspect a single cylindrical structure. Usually, the HEs are arranged in an array, and circumferential guided waves are used for …

WebAug 19, 2024 · For an array of applications of the high voltage pulse discharge technology in reservoir stimulations and to gain a deeper understanding of the fractures mechanism of deep well rock under cyclic electrohydraulic shock waves (EHSWs), the effect of confining pressure and hydrostatic pressure on the fracturing of rock under EHSWs are … WebOct 27, 1998 · The guided circumferential waves induced by this transient excitation are studied in detail to understand the propagation characteristics of various wave modes. The method of eigenfunction expansion is used to solve the transient wave propagation problem. WebIn the physical sciences, the wavenumber (also wave number or repetency [1]) is the spatial frequency of a wave, measured in cycles per unit distance ( ordinary wavenumber) or radians per unit distance ( angular wavenumber ). [2] [3] [4] It is analogous to temporal frequency, which is defined as the number of wave cycles per unit time ... man redruth
