Numerical simulation of the vaporization of multi-component liquid fuels under high-pressure conditions is conducted in this study. A high-pressure drop vaporization model is developed by considering the high-pressure phase equilibrium which equates the fugacity of each component in both liquid and vapor phases. Peng-Robinson equation of state is used for the calculation of fugacity. To model t...

This paper deals with the heat exchange performance prediction of a counter flow double-tube condenser for binary natural refrigerant mixtures (propane/n-butane & propane/i-butane ). The local characteristics of the heat transfer and pressure drop are calculated using a prediction method developed by authors, and the total pressure drop, the overall heat transfer coefficient and the average hea...

Coiled tubing (CT) is widely used in drilling, workover, completion, fracturing and stimulation the field of oil gas exploration development. During CT operation, will present a gas–liquid two-phase flow state. The prediction frictional pressure drop for fluid tube an important part hydraulic design, its accuracy directly affects success technique. In this study, we analyzed effects void fracti...

Abstract The monitoring of large-scale natural gas pipelines is vital to their reliable and effective operation. To the lack data analysis operation advice functions in existing systems, this work established a pipeline system. working state was uncovered with reconciliation thermodynamical models. Temporal load distribution depicted for monitoring. Based on historical data, compressor numbers ...

The largest two-shaft gas turbine in the United States has been operated in combined cycle service at the Oklahoma Gas and Electric Company Horseshoe Lake Station since May 1963. The same design unit has been operated in peaking and stand-by service at Public Service Electric and Gas (Essex, N. J.) station since December 1963. The 0.G & E. unit has a NEMA rating of 25 Mw base load. The PSEG uni...
