Study on influence of flow rates on voids in waxy crude oil subjected to dynamic and static cooling [PDF]

open access: yesJournal of Mechanical Engineering and Sciences, 2015
The assumption of constant yield stress in the conventional restart pressure equation neglects the effects of thermal shrinkage and gas voids formation, which in turn resulted in an over-designed production piping systems.
