Theoretical and Numerical Studies on Continuous Detonation Wave Engines

Numerical simulation of a Rotating Detonation with a realistic injector designed for separate supply of gaseous hydrogen and oxygen

“…In a first step, the rotating detonation is often studied in small combustion chambers but demonstration chambers are now in development or testing [12]. Semi-analytical and simple 0D models have been developed to evaluate the theoretical performance of RDE, as in [13,14]. Even 15 if parametric studies are more complex with 2D/3D numerical tools, numerical simulations are now commonly used, as in [15,16,17,18,19,14,20,21], because they can depart from too simplifying assumptions and give a deep insight into the flow physics.…”

Experimental investigation on detonation combustion patterns of hydrogen/vitiated air within annular combustor

“…CRD has been investigated widely in recent years, including in Russia [5][6][7][8][9], the USA [3,[10][11][12][13], France [14][15][16], Poland [2,17,18], China [4,[19][20][21][22] and so on. Two propagation modes of CRDW, referred as homo-rotating mode and hetero-rotating mode here, were found in experiments.…”

Experimental verification of air-breathing continuous rotating detonation fueled by hydrogen

“…Continuous rotating detonation (CRD) is one way to achieve detonation combustion, by utilizing detonation waves that circles continuously in a usually adopted annular combustor. The phenomena is thus referred to as the continuous spinning detonation (CSD) [1], rotating detonation [2e4], continuous detonation [5] or CRD [6].…”
