Effects of roll motion on air distribution and frictional resistance of an air-lubricated container ship

Air lubrication technology reduces ship frictional resistance by injecting air beneath the hull, yet how ship roll motion alters the near-wall air distribution and frictional resistance response remains poorly understood. This study uses full-scale unsteady Reynolds-averaged Navi...

Shipboard core-storage platform for drillships: design, verification and field validation

For the pioneered shipboard automated core-transmission system (ACTS) on the ocean drillship Dream, the structural integrity and operational reliability of the storage rack subsystem are critical to core logistics efficiency. The shipboard subsystem module experiences pronounced...

CatalyticPerformance and Reaction Mechanism of Coand Zn-Codoped Fe Catalysts on Different Supports for CO2 Hydrogenation

Abstract Metal oxides are commonly used as supports for catalysts for CO2 hydrogenation. However, systematic studies on the influence of different metal oxide supports on the catalytic performance of catalysts for light olefin production remain limited. Therefore, a series of cob...
