Fundamentals and Applications of Pressure Gain Combustion

Fundamentals and Applications of PGC














Instructed by experts from the AIAA Pressure Gain Combustion Technical Committee

Overview
Unlike conventional isobaric combustion, pressure gain combustion (PGC) is focused on technologies that are able to increase the pressure of the working fluid through the combustion process without the need for additional mechanical compression.  PGC can be achieved with either deflagration or detonation although the mechanism for pressure gain would be different depending on the method of combustion. Regardless of the approach, PGC offers greater work availability compared to isobaric combustion, but it has unique challenges. As a result of the potential improvement in cycle efficiency, as well as advances in computational and experimental methods, there has been a growing interest in PGC for applications in aerospace propulsion and power generation.

This course provides an overview of the unique aspects of PGC.  The course introduction will begin with a historic perspective of PGC and include thermodynamic theory comparing PGC to other relevant power cycles.  This is followed by an overview of several major classes of PGC such as Pulse Combustion, Wave Rotor Combustion Engines (WRCE), Pulse Detonation Engine (PDE) and Rotating Detonation Engines (RDE).  As PGC research has its own unique challenges, the course offers a review of relevant and state-of-the-art computational and experiments methods that are utilized in both fundamental and more applied studies.  The course will include a discussion of systems integration along with lessons learned from some demonstrated applications. Government funded programs have been critical and the course will include an overview of the various programs and potential roadmaps for helping to advance the technology forward. Instructors from this course come from various reaches of technology development including fundamental research, program direction and industry.
