Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and

Limitations of Navigation by the FSCIR Ice Class A1 Ship in Polar Waters [PDF]

TransNav
The FSCIR A1 ice class ships are designed to navigate in non-Arctic waters, but they may operate in polar waters under specified ice conditions. This work took into consideration speed and ice conditions limiting movement of the ship in ice during ...

Prediction of Properties of Polymer Composite Formulations Using Ensemble Models With Feature Generation

Journal of Applied Polymer Science, EarlyView.
This study develops an interpretable machine‐learning framework to predict multiple properties of polymer composites based on composition and processing variables. By combining ensemble models with composition‐based feature generation and SHAP‐based interpretation, the approach reveals composition‐property relationships and supports efficient multi ...

Roll motion characteristics of a polar research ship with ice accumulation in beam waves

International Journal of Naval Architecture and Ocean Engineering
Stability of polar vessels could be deteriorated due to ice accumulation, making it crucial to investigate the dynamic behavior of the vessel under harsh polar conditions. In this work, the effect of ice accumulation on the roll motion characteristics of

Arctic shipping and polar seaways

, 2020
Climate change in the Arctic triggered a series of discourses about the opening-up of a previously unreachable region. Navigation remains however difficult in the Arctic, transits are still very limited, as sea-ice still is a major constraint. How did the development policies of both the North West Passage and the Northern Sea Route unfold ?

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Seasonal changes in planktonic bacterivory rates under the ice-covered coastal Arctic Ocean [PDF]

, 2008
Bacterivory was determined in surface waters of Franklin Bay, western Arctic, over a seasonal ice-covered period (winter-spring, 2003-2004). The objectives were to obtain information on the functioning of the microbial food web under the ice, during ...
