Establishment and Analysis of a General Mass Model for Solenoid Valves Used in Space Propulsion Systems

Mathematics
The solenoid valve component is the core part affecting the total mass of space propulsion system, and the accuracy of the solenoid valve mass model directly impacts the accuracy of the system mass estimation and optimization design.

Low-carbon ammonia-based fuel for maritime transport

Results in Engineering
The review examines decarbonized ammonia as a promising fuel for marine transportation. When ammonia burns, it does not produce carbon dioxide and its energy density is 23 MJ/kg. Liquid ammonia has a volumetric energy density of 15,600 MJ/m3.
