Acoustics of Corrugated Pipes: A Review

Applied Mechanics Reviews, 2013
Corrugated pipes and tubes are commonly used in many engineering and industrial applications because they offer global flexibility combined with local rigidity. Some of the engineering systems which use the corrugated pipes are Liquefied Natural Gas (LNG) storage systems, risers for offshore oil and gas industries, heat, ventilation, and air ...

Singing corrugated pipes revisited

American Journal of Physics, 1994
A long corrugated tube open at both ends sings notes which depend on the flow velocity of air flowing through the tube. The notes it sings are natural harmonics of the tube. In 1974, Crawford suggested an explanation for this: A given note will sing when the flow velocity is such that the ‘‘bump frequency’’ equals the frequency of the note, provided ...

Experiments on sound generation in corrugated pipes with flow

The Journal of the Acoustical Society of America, 2007
The article reports acoustic measurements on short corrugated pipes with flow. Such pipes might generate high sound levels associated with length resonances. One of the main objectives of the study was to estimate the location of the effective sources by studying the energy flow through the pipes.

On whistling of pipes with a corrugated segment: Experiment and theory

Journal of Sound and Vibration, 2013
Corrugated pipes are commonly used because of their local rigidity combined with global flexibility. The flow through such a pipe can induce strong whistling tones, which is an environmental nuisance and can be a threat to the mechanical integrity of the system.

PVC corrugated drainage pipe

Journal of Vinyl Technology, 1981
Abstract In the continuing struggle to obtain the most economical material for a given application, it is proposed that corrugated PVC can be quite competitive with corrugated PE. An advantage for PVC stems from a flexural modulus that is almost twice that of PE.

Whistling of Short Corrugated Pipes: Experimental Investigation of the Source Locations

16th AIAA/CEAS Aeroacoustics Conference, 2010
The goal of this study is to investigate the issue of the aeroacoustic source location within corrugated pipes. For this purpose, a configuration with a short pipe and well defined boundary conditions is chosen. These investigations have been carried out focusing on the first two whistling modes.

Cryogenic Structural Performance of Corrugated Pipe

29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 6, 2010
One alternative to developing offshore gas reserves is to use a floating LNG plant (FLNG) on site and export the LNG using tankers. This alternative requires the use of a reliable LNG transfer system between the FLNG and the tanker under offshore conditions.

Heat Transfer Enhancement in Corrugated Pipes

2010 14th International Heat Transfer Conference, Volume 2, 2010
The temperature distribution and heat transfer coefficient are investigated in forced convection with Newtonian fluids in pressure gradient driven hydrodynamically and thermally fully developed steady laminar flow in transversally corrugated pipes. The governing equations are solved by means of the epitrochoid conformal mapping and exact analytical ...

Corrugated Pipe Flow Rate from Pipe Geometry

Journal of Irrigation and Drainage Engineering, 1984
Corrugated plastic drainage tubing has been available in North America for only 15 years. It now represents 75% of the drainage pipe used in agriculture for subsurface drainage. Hydraulic tests are available for diameters from 35 mm–300 mm, however, this type of tubing is now available to 750 mm.
