Investigation of Pulse Detonation Engines: the Effect of Variable Blockage Ratio on the Deflagration to Detonation Transition
<p>Detonation and constant volume combustion is well known to be thermodynamically more efficient than the typically utilized constant pressure. There have been numerous approaches of achieving detonation through deflagration-to-detonation transition most of which use evenly spaced obstacles with a …
