This course will provide an introductory overview to the new field of Pressure Gain Combustion (PGC), with a special focus on the cutting edge technology of Rotating Detonation Combustion. Students will gain familiarity with the fundamental concepts underlying PGC and RDC technology as well as the challenges being addressed and the techniques being used to advance these state-of-the-art combustion devices.
