Double-curved pipes are widely employed as essential components of subsea pipeline systems. Considering the layout flexibility and application diversity, there various spatial structures for double-curved combinations. However, few studies have compared flow characteristics in different pipes. The dissipations corresponding downstream not been thoroughly investigated, which crucial measurement ...

A distributed Brillouin fiber sensor has been employed to detect localized pipe-wall buckling in an energy pipe by measuring the longitudinal and hoop strain distributions along the outer surface of the pipe for the first time. The locations of the localized pipe-wall buckling are found and distinguished using their corresponding strain-load data. The formation of the buckling process for the c...

Buried water and gas pipe systems form part of critical infrastructure providing essential services to the community. In many global population centres including in Australia, this vital infrastructure has been installed several decades ago, and dealing with frequent pipe failures become a major problem. There are clear evidences that pipe failures significantly depend on pipe strains induced b...

This paper determines most common model of in-pipe robots to derive its degree of freedom in order to compare with the necessary degree of freedom required for a system to move inside pipelines freely in order to derive analytical reason for losing control of in-pipe robots at branched pipe. DOF of most common mechanism in in-pipe robots can be calculated by considering the robot as a parallel ...

OBJECTIVES A water pipe (hookah) is a tobacco smoking tool which is thought to be more harmless than a cigarette, and there are no adequate studies about its hazards to health. Water-pipe smoking is threatening health of the youth in the world today. The objective of this study has been to investigate the carbon monoxide (CO) levels in breath, examine the changes in pulmonary function tests (PF...

The turbulent pulsating flow and heat transfer in straight 90° curved square pipes are investigated this study. Both experimental temperature field measurements at the cross-sections of conjugate (CHT) simulation were performed. steady was compared to under same time-averaged Reynolds number. number flow, as well approximately 60,000. Womersley 43.1, corresponding a 30 Hz frequency. Meanwhile, ...
