Coordinated control of gas supply system in PEMFC based on multi-agent deep reinforcement learning
International journal of hydrogen energy, 2021In proton exchange membrane fuel cells (PEMFCs), the hydrogen supply system and air supply system jointly impact the output characteristics, and there is a coordination problem between these two systems. To solve this coordination problem, an intelligent

SIMULATION OF THE GAS MIXING PROCESS OF THE FUEL SUPPLY SYSTEM
Modeling of systems and processes, 2020The article discusses the methods of modeling gas mixing, leading to more intense gas mixing, for the most complete combustion of the resulting turbulent jet, which is used in combustion processes. The necessity of the proposed model is proved: by summing the concentrations of the components in the zones of fuel and oxidizer; stoichiometric flow of ...

Conceptual Model of Analysing Risk in a Fuel Gas Supply System (FGSS) on LNG Fuelled-gas Vessel
Proceedings of the 3rd Asia Pacific Conference on Research in Industrial and Systems Engineering 2020, 2020This study aims to propose a risk analysis framework using the FMEA method and system dynamics approach. FMEA is used as a first stage to identify critical equipment/ system based on the highest RPN, then uses the value of the O (Occurrence) as an input to simulate the extent of the effectiveness of the costs incurred and to see the possibility of a ...

Fault Diagnosis and Prognosis for Fuel Supply System in Gas Turbine Engines
Volume 1: 20th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2005A fault diagnosis and prognosis method is developed for the fuel supply system in gas turbine engines. The engine startup profiles of the core speed (N2) and the exhaust gas temperature (EGT) collected with high speed sampling rate are extracted and processed into a more compact data set.

Experimental studies of the locomotive gas-diesel engine with electronic fuel supply control system
Proceedings of Higher Educational Institutions. Маchine Building, 2023Fuel efficiency and exhaust gases toxicity are the main indicators of the locomotive diesel operation. To increase them, the paper proposes to convert the locomotive diesel to working on natural gas. Expediency of such conversion to operate on the natural gas according to the gas-diesel cycle, where natural gas being the main gaseous fuel is ignited ...

Fault diagnosis and prognosis for fuel supply systems in gas turbine engines
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2008This paper introduces a feature-extraction method to characterize gas turbine engine dynamics. The extracted features are used to develop a fault diagnosis and prognosis method for the fuel supply system in gas turbine engines. The engine start-up profiles of the core speed (N2) and the exhaust gas temperature collected with high-speed sampling rate ...
