A steady-state model for heat pipes of circular or rectangular cross-sections
(1996-08-01)
The objective of this paper is to present a generalized analytical-numerical model of the internal flow in heat pipes. The model formulation is based on two-dimensional formulation of the energy and momentum equations in ...

Wavespeed measurement in buried water distribution pipes and its significance in leak location
(2013-09-16)
To determine the location of leaks in buried water pipes, acoustic methods are often used. These have proven to be very effective in metallic pipes but have been problematic in modern plastic pipes. In this paper the reason ...

Piping process: Genesis and network characterization through a pedological and geophysical approach
(2020-03-01)
Piping is a soil erosion process initiated by concentrated subsurface water flow, which can develop in both natural and anthropogenic landscapes and causes various environmental impacts. The piping process acts as a relief ...
On the effects of soil properties on leak noise propagation in plastic water distribution pipes
(2018-08-04)
In many countries, leaks are located in water distribution pipes by using the cross-correlation of pipe vibration measured either side of a suspected leak. However, in modern plastic pipes this can be problematic due to ...
