...Steven P. Smith; Garry A. Gregory; Harvey W. Yarranton The mechanistic model of Taitel and Dukler [1] has previously been reported to exhibit a region in which three solutions exist for the height of the gas-liquid interface in the stratified/wave flow regime. Most laboratory studies have not dealt...

...Shoubo Wang; Luis E. Gomez; Ram S. Mohan; Ovadia Shoham; Gene E. Kouba Gas-Liquid Cylindrical Cyclone (GLCC© 1 ) separators are becoming increasingly popular as attractive alternatives to conventional separators as they are simple, compact, less expensive, have low-weight, and require little...

... scheme to ensure that both existing and new hydrogen technologies are implemented without endangering public safety. In this plan, we consider the transport and storage of a large quantity of hydrogen in a large tank. First we must evaluate the consequence of the postulated accident of liquid hydrogen...

...B. G. Shiva Prasad, Mem. ASME Compressors are intolerant to liquids. In reciprocating compressors with inherently large volumetric displacement rates, all modes of liquid ingestion pose a serious problem and can even result in catastrophic failures. This paper describes a simple method...

...E. J. Anthony; D. Y. Lu; J. Q. Zhang Liquid fuels such as bitumen, tars, and pitches are byproducts of heavy oil upgrading processes, and are usually contaminated with high sulphur and sometimes heavy metals contents as well. Fluidized bed combustion (FBC) appears to be a promising technology...

...Hoi C. Yeung; Paulo C. R. Lima More and more transient gas-liquid operations in pipes have been successfully applied in the oil and gas industry. Pigging operation in two-phase pipelines to remove liquid accumulation or for cleaning purpose is an important transient operation. Another important...

...A. O. Nieckele; A. M. B. Braga; L. F. A. Azevedo Simulation of the transient motion of pigs through liquid and gas pipelines is presented. The differential form of the mass and linear momentum equations for compressible liquid and gas flows were solved by a finite difference numerical technique...

...Antonio C. Bannwart, Assoc. Mem. ASME A theory for the stabilization of annular liquid-liquid flow (i.e., core-annular flow) in a horizontal pipe is proposed. Based upon the analysis of the momentum conservation equation in the cross section of the flow, including the effects of peripheral flow...

...Shoubo Wang; Ram S. Mohan; Ovadia Shoham; Jack D. Marrelli; Gene E. Kouba The performance of gas-liquid cylindrical cyclone (GLCC©) separators for two-phase flow metering loop can be improved by eliminating liquid overflow into the gas leg or gas blow-out through the liquid leg, utilizing suitable...

...X. Tom Chen; Hong-Quan Zhang; Clifford L. Redus; James P. Brill Gas-liquid downward flow is frequently encountered in hilly-terrain pipelines, downcomer pipes extending from offshore production platforms to sea floors, and steam injection wells in thermal enhanced recovery operations. Since...
