Aeroacoustical coupling and synchronization of organ pipes
The Journal of the Acoustical Society of America, 2016A synchronization experiment on two mutual interacting organ pipes is compared with a theoretical model which takes into account the coupling mechanisms by the underlying first principles of fluid mechanics and aeroacoustics. The focus is on the Arnold-tongue, a mathematical object in the parameter space of detuning and coupling strength which ...

Coupling impedance of a hole in a coaxial beam pipe
Physical Review E, 1996n this paper we derive the impedance of a circular hole in the inner tube of a coaxial beam pipe. The method used differs from the classic Bethe's diffraction theory, since, in the calculation of the magnetic and electric dipole moments, we take into account also the scattered fields in the aperture to match the power conservation law.

Coupled consolidation analysis of pipe–soil interactions
Canadian Geotechnical Journal, 2013Current design practice for pipe–seabed interaction in soft soils is generally based on the assumption of undrained behaviour throughout laying and subsequent operation. In reality, drainage and consolidation around a partially embedded pipe can have a marked effect on the vertical penetration and horizontal breakout resistance. In this paper, a large-

On the Suppression of Coupled Liquid/Pipe Vibrations
1996The vibration of liquid-filled pipe systems can be caused by internal (pressure surges) or external (rotating machinery) sources, or a combination of both. Liquid pulsations can be diminished by devices like an air chamber, whereas pipe vibrations can be reduced by suitable supports.

Journal AWWA, 1918
The object of this paper is to discuss the joints commonly used in service pipe connections and the development that has taken place from time to time under the guiding light of experience, for the purpose of improvement and prolonging the life of the service and its various appurtenances.

SYNCHRONIZATION OF HIGHER HARMONICS IN COUPLED ORGAN PIPES
International Journal of Bifurcation and Chaos, 2007We report results on the synchronization of two organ pipes positioned side by side. Special attention is put on the synchronization of the higher harmonics. As possible explanation, classical theory provides the amplitude death as explanation for the reduction to almost silence of two coupled organ pipes.

The coupled dynamics of foam generation and pipe flow
International Journal of Heat and Fluid Flow, 2019Abstract Foam generation in porous media and foam flow through pipes have been studied extensively to date as uncoupled processes. The coupled dynamics of foam generation and pipe flow, however, are comparatively understudied, despite their importance to industrial applications.

Coupled Non-Equilibrium Processes in Heat Pipes
Journal of Non-Equilibrium Thermodynamics, 1989A gravity assisted capillary heat pipe is viewed as a direct energy convertor capable of transforming thermal power into hydraulic power, but operating conventionally in the «short-circuit» mode (i.e., no output power). It is demonstrated that the formalism, based on the Onsager Reciprocal Theorem of linear irreversible thermodynamics, developed in ...

Pipe Coupling Techniques for Marine Pipelines
Proceedings of Fall Meeting of the Society of Petroleum Engineers of AIME, 1968American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. Discussion of this paper is invited. Three copies of any discussion should be sent to the Society of Petroleum Engineers office. Such discussion may be presented at the above meeting and, with the paper, may be considered for publication in one of the two SPE ...
