Autoignition in stratified mixtures for pressure gain combustion
Proceedings of the Combustion Institute, 2021The reliable generation of quasi-homogeneous autoignition inside a combustor fed by a continuous air flow would represent a milestone in realizing pressure gain combustion in gas turbines. In this work, the ignition distribution inside a stratified fuel–air mixture is analyzed. The ability of precise and reproducible injection of a desired fuel profile

Pressure Gain Combustion by Using Shock Flame Interaction Pressure Rise
Volume 5: Controls, Diagnostics, and Instrumentation; Cycle Innovations; Cycle Innovations: Energy Storage, 2020Abstract Pressure loss across a combustor in a gas turbine reduces thermal efficiency and increases specific fuel consumption. Theoretically, any pressure gain across the combustor results in higher thermal efficiency and lower specific fuel consumption.

Thermal analysis and performance of a pressure gain combustion system
2017Conventional gas turbine engines burn fuel in a steady state combustor at constant pressure, and the pressure rise is obtained by the compressor driven by the turbine. In the Pressure Gain Combustion cycle, the combustion process is at constant volume, allowing an increase of the pressure without the need of the compressor.

Pressure-Gain Combustion Using Shock–Flame Interaction
Journal of Propulsion and Power, 2013One method of significantly improving the performance of gas turbine engines is to use the thermodynamically more efficient unsteady combustion with pressure rise. In this work, the feasibility of using the interaction of shock waves with a flame to achieve pressure-gain combustion is investigated. A new analytical model is described. The pressure rise

Steam injected Humphrey cycle for gas turbines with pressure gain combustion
Energy, 2019Abstract Gas turbines are a mature technology and any increase in their efficiency comes at high R&D cost. Pressure Gain Combustion (PGC) has emerged as a concept to significantly improve their efficiency. Technically, PGC is realized through detonative combustion or approximations of constant volume combustion.

Active Valve Resonant Pulse Combustor for Pressure Gain Combustion Applications
Journal of Propulsion and Power, 2022This work is an experimental demonstration of a novel resonant pulse combustor technology for which sustained pressure gain can be achieved at thermal equilibrium. The resonant pulse combustor employs an actively driven air inlet valve with passively modulated fuel injection such that the device operating frequency is specified by the valve set-point ...
