Determining the Pressure Gain of Pressure Gain Combustion [PDF]
2018 Joint Propulsion Conference, 2018 Over the past few decades, there has been significant research into propulsion concepts attempting to employ pressure gain combustion. Pressure gain combustion concepts to date have resulted in dynamic, non-uniform gas flows which are difficult to characterize and compare with more conventional forms of propulsion.

The Influence of Unsteadiness on the Analysis of Pressure Gain Combustion Devices [PDF]
51st AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2013 Pressure gain combustion has been the subject of scientific study for over a century due to its promise of improved thermodynamic efficiency. In many recent application concepts, pressure gain combustion is used as a component in an otherwise continuous, normally steady flow system, such as a gas turbine or ramjet engine.

Effects of Al/O on pressure properties of confined explosion from aluminized explosives
Defence Technology, 2017 Pressure histories were tested in a 500-L chamber to identify the pressure load in confined explosion from aluminized explosives. Different aluminized explosives with Al/O, ranging from 0.25 to 1.23, were used.
