Abstract: A quasi-two-dimensional two-phase flow cylindrical model of slug motion in a voided line is developed that can reasonably predict the change of flow pattern of the slug, air entrainment, “holdup” ...

Abstract: Gaseous cavitation, alternately termed gas release, is investigated for turbulent pipe flows subjected to transient wave motion. Experimental data are presented that exhibit developing two-component ...

Abstract: Observed damage and analytic studies indicate that earthquakes may cause destructive pressure surges in liquid-filled piping. Most studies have concerned buried piping that could be assumed to ...

Abstract: Water hammer pressure in piping is modified by the consequent motion of the piping. In general, accurate estimates of dynamic pressure and pipe displacement must account for this interaction. ...

Abstract: Transient pressure in piped liquid is a function of structural restraint at elbows. If supported rigidly, an elbow causes no appreciable alteration of the pressure transient generated by rapid ...

Abstract: It is well known that the magnitude of the acoustic wavespeed in piping is influenced by properties of the fluid and the pipe material. Traditionally, derivations have been based on a ...

Abstract: Pipe vibrations can be induced by internal liquid pulsations which propagate throughout the piping system and create unbalanced oscillatory pressure forces at locations where either flow area or ...

Abstract: Since liquid-filled piping systems are composed of slender elements, their transient behavior can be described as one-dimensional wave phenomena. Seven wave components are identified: coupled axial ...
