Aerodynamic Investigation of Guide Vane Configurations Downstream a Rotating Detonation Combustor [PDF]

Volume 4B: Combustion, Fuels, and Emissions, 2020
Abstract Pressure Gain Combustion (PGC) is considered a possible solution to increase gas turbine cycle efficiency, due to the lower entropy generation in the combustion process. However, the highly unsteady flow produced by PGC makes it more difficult to extract work from its exhaust gas.

Performance Analysis of Pulse Detonation Micro Gas Turbines Under Typical Operating Conditions

Energy Science &Engineering, Volume 13, Issue 10, Page 4690-4703, October 2025.
ABSTRACT Considering the benefits of pulse detonation combustion, including low entropy increase, high cycle thermal efficiency, and self‐pressurization, a performance calculation model for a pulse detonation micro gas turbine was established using methane as fuel. The study primarily investigated the impact of component parameters, ambient conditions,

Coal dilemma: Is in situ clean power plant a way out?

EcoEnergy, Volume 2, Issue 2, Page 220-228, June 2024.
New clean power generation system based on controlled pulverized coal detonation. Abstract The global shift toward cleaner energy sources, driven by carbon neutrality goals and climate change urgency, faces a paradoxical rise in coal consumption despite efforts to expand alternative energies. Economic disparities drive reliance on coal, particularly in
