THE IMPACT OF A CONVERGING-DIVERGING NOZZLE ON PDE PERFORMANCE AND ITS ASSOCIATED FLOWFIELD

Performance impact of a converging-diverging nozzle on a pulsed detonation engine (PDE) is studied experimentally. Thrust and specific impulse are determined from integrated pressure measurements. Burned gas velocity is obtained from optical measurements of seeded cesium atom. Comparison of measured quantities with prediction from finite-rate chemistry computational fluid dynamics (CFD) models indicate heat transfer plays a significant role at late times during blowdown.
