Published: Feb. 16, 2023

This paper reviews research in ocean engineering over the last 50+ years with aim to (I) understand technological challenges and evolution field, (II) investigate whether studies meet present global demands, (III) explore new scientific/engineering tools that may suggest pragmatic solutions problems, (IV) identify management gaps, way forward. Six major divisions are identified, namely Ocean Hydrodynamics, Risk Assessment Safety, Climate Geophysics: Data Models, Control Automation Ocean, (V) Structural Engineering Manufacturing for (VI) Renewable Energy. As much as practically possible sub-divisions of field also identified. It is highlighted topics dealing renewable energy, control path tracking ships, well computational modelling wave-induced motions growing. Updating forecasting energy resources, developing methods wave generation, introducing novel optimised converters potential opportunities. Ongoing follow needs environmentally friendly energies, though engineering-based often tend overlook longer-term influence climate change. Development exploitation focus on continuum mechanics problems remain relevant. Notwithstanding this, machine learning attracting attention researchers.

An Overview of the Recent Advances in Composite Materials and Artificial Intelligence for Hydrogen Storage Vessels Design

Journal of Composites Science, Journal Year: 2023, Volume and Issue: 7(3), P. 119 - 119

Published: March 14, 2023

The environmental impact of CO2 emissions is widely acknowledged, making the development alternative propulsion systems a priority. Hydrogen potential candidate to replace fossil fuels for transport applications, with three technologies considered onboard storage hydrogen: in form compressed gas, as cryogenic liquid, and solid. These are now competing meet requirements vehicle manufacturers; each has its own unique challenges that must be understood direct future research efforts. This paper reviews technological developments Storage Vessel (HSV) designs, including their technical performance, manufacturing costs, safety, impact. More specifically, an up-to-date review fiber-reinforced polymer composite HSVs was explored, end-of-life recycling options. A current numerical models conducted, use artificial intelligence techniques assess performance HSVs, leading more sophisticated designs achieving sustainable future.

Recovery in the wake of in-line axial-flow rotors

Physics of Fluids, Journal Year: 2022, Volume and Issue: 34(4)

Published: April 1, 2022

The flow around the rotor of an axial turbine, operating in wake upstream one, is resolved using large-eddy simulation on a cylindrical grid consisting 3.8 billion points. Three distances from are considered, ranging 6 to 10 diameters. inflow boundary conditions for downstream were generated by precursor one. impact dynamics tip vortices and statistics at their core compared across cases. Results demonstrate strong sensitivity shed disturbance produced onset instability moves very close plane almost independent distance between rotors, least range simulated distances. This makes development driven vortices, much faster similar results explain phenomena performance stabilization turbines linear arrays, recently reported literature.
