Time domain phenomenological formulation for the sound generation in corrugated pipes

Sounding Mechanism of a Flue Organ Pipe—A Multi-Sensor Measurement Approach

“…• The pipe wall is set into motion by the acoustic waves (vibration-mechanical system). Moreover, it can also be claimed that, by the end of the 20th century, research was mainly developed in the following two areas: the theoretical approach based on physical theory and formulas [18][19][20][21][22] and a practical approach focusing more on measurements and the analyses of experimental data [23][24][25][26][27][28][29][30]. In recent years, thanks to a massive growth of computational power and the development of new software, the third thread of research became prominent, namely the numerical simulation and modeling of aerodynamics as well as acoustic and mechanical systems [29,31,32].…”

“…This can match the reality in many cases, but, especially the jet, it is sensible to many variables and can be influenced by asymmetries or irregularities along the width of the flue, as underlined by Rucz et al [31]. For example, it Moreover, it can also be claimed that, by the end of the 20th century, research was mainly developed in the following two areas: the theoretical approach based on physical theory and formulas [18][19][20][21][22] and a practical approach focusing more on measurements and the analyses of experimental data [23][24][25][26][27][28][29][30].
