The LNG Flow Simulation in Stationary Conditions through a Pipeline with Various Types of Insulating Coating

Liquefied natural gas (LNG) is one of the most promising fuels for energy supply because it has a favorable combination environmental and economic properties in connection with new trends aimed at development ecological sustainable consumption resources, which ensure constant growth LNG consumption. The article presents an analytical review main technical solutions construction cryogenic pipelines insulating coating structures. ANSYS Fluent software was used simulation flow pipeline section 10 m long outer diameter 108 mm three types (polyurethane (PU) foam, aerogel, vacuum-insulated pipe (VIP)). In addition, assessment made effect on temperature distribution along length pipeline. largest increase from 113 K to 113.61 occurs PU foam-insulated pipes; smallest observed VIP. Further, as alternative steel, use ultra-high molecular weight polyethylene (UHMWPE) material considered. optimal result terms distributions obtained while simulating foam by increasing thickness 0.05 m.
