The heat and mass exchange of CO2 in a vertical U-tube under supercritical pressure was simulated.The effects of the geometry of the bend area, The center arc radius of the bend area and the different bend orientations on the flow heat transfer of supercritical CO2 in the U-tube were analyzed.The results show that in the bend area, handheld-machine
Carbon-nanotube (CNT) is a promising material owing to its compelling mechanical, thermal and electrical properties and has been applied in a broad variety of fields such as composite, fiber, film and microelectronic.Although the introductions of CNT have brought huge improvement for many applications, these properties of macrostructures prepared b

Since 2002, the China Geological Survey has successively organized and implemented hydrogeological survey and groundwater exploration in water deficient areas, such as severe water shortage areas in west China, Wumeng Mountain area, Yimeng mountain area and red bed area in southern Jiangxi, obtained a large number of exploration data conducive to p
Marine flexible pipe/cables, such as umbilicals, flexible pipes and cryogenic hoses, are widely adopted in ocean engineering.The reinforcing armor Tear Stain Remover layer in these pipe/cables is the main component for bearing loads, which is a typical multi-layer helically wound slender structure with different winding angles for different devices
