Simulation and performance analysis of a heat transfer tube in SuperORV

LNG Regasification Terminals: The Role of Geography and Meteorology on Technology Choices

“…Added to this, in the case of ORV, it must also deal with the corrosive nature of seawater [6]. The racks are constructed of finned aluminium tubing providing strength against the cold operating temperatures and are coated with corrosion protection where they are in contact with salt water [14].…”

“…While there is a reasonable amount of literature from industry and conference sources on LNG regasification terminals globally, its quality is variable and must be interpreted with skill and care. The literature review consisted of only eight key peer-reviewed papers; 3 papers are on LNG cold energy utilization [2][3][4], 1 paper on thermal design of IFV [5], 1 paper on Super ORV heat transfer simulation [6], 1 paper on AAV practical application [7], 1 paper on fog clouds due to ambient air vaporizer [8] and 1 paper on materials and corrosion aspects in LNG regasification terminals [9].…”

Design of an Intermediate Fluid Vaporizer for Liquefied Natural Gas

“…For example, proper corrections of the logarithmic mean temperature difference should be included for the IFVs containing multiple tube and/or shell passes. Appropriate methods for quantification of heat transfer area and applicable HTC correlations should be established for IFVs utilizing enhanced tubes, e.g., the tubes with finned or grooved surfaces, for heat transfer process intensification . On the other hand, the multicomponent LNG mixture is predominantly approximated by pure methane in the open literature.…”

“…The Bergles-Rohsenow [39] and the Chen method [40] were adopted for HTC predictions of the internal subcooled and saturated flow boiling, respectively. As for the mist flow boiling, the modified Dittus-Boelter equation with the average properties of the pseudo-fluid is applied for the HTC estimation [8,41]. General characteristics of the subcritical flow boiling curve have been successfully predicted, including the fast increase after nucleate boiling initiation, the inflection after partial dryout, and the sharp decrease after nucleate boiling suppression [40] (Fig.…”

Thermal performance analysis of SuperORV heat transfer tube at supercritical pressure

“…Hisada and Sekiguchi (2004) developed highly endurable structures for ORV through various tests or analysis by the finite element method, and attained best-suited shapes of ORV heat transfer tubes by using numerical analysis and thermal stress design. Jin et al (2014) established a distributed parameter model based on energy balance to simulate the LNG evaporating process in a SuperORV heat transfer tube. In above model, the thickness of ice layer formed outside the heat transfer tube was considered to be a constant or decrease linearly along tube length, the length of ice layer was calculated by trial and error according to the practical length of heat transfer tube, and the LNG in annular channel between outer and inner tubes was supposed to be superheated vapor at the inlet of heat transfer tube.…”
