Reactant mixing and combustion are investigated in an optically accessible, self-excited
linear detonation combustor. The mixing field is captured using 100 kHz planar laser …

The influence of transverse concentration gradients on detonation propagation in H _2 H 2–
air mixtures is investigated experimentally in a wide parameter range. Detonation fronts are …

A variably premixed rotating detonation engine using gaseous hydrogen and air reactants is
introduced to enable investigation of key cycle processes while varying the homogeneity of …

Behavior of detonation waves in mixtures with concentration gradients normal to the
propagation direction was studied experimentally. Mixtures with various concentration …

The propagation of detonations through several fuel–air mixtures with spatially varying fuel
concentrations is examined numerically. The detonations propagate through two …

In detonation engines and accidental explosions, a detonation may propagate in an
inhomogeneous mixture with non-uniform reactant concentration. In this study, one-and two …

Pressure gain combustion (PGC) has gained significant attention in airbreathing gas turbine
applications due to its increased thermodynamic efficiency over a constant-pressure Brayton …

Systematic three-dimensional numerical simulations of flame acceleration and deflagration-
to-detonation transition (DDT) in a semi-confined flat slit combustor are performed. The …

The role of a transversal concentration gradient in detonation propagation in a two-
dimensional channel filled with an bump and thus the unreacted pocket behind the front …

Ignition in a supersonic mixing layer interacting with an oblique shock wave is investigated
analytically and numerically under conditions such that the post-shock flow remains …
