Numerical simulation of continuously rotating detonations of stoichiometric two-fuel mixture with air has been carried out for the cylindrical annular detonation chamber (DC) of the rocket-type engine. The syngas (1-α)СO+αH2, a binary mixture of hydrogen H 2 and carbon monoxide CO, is taken. We studied the global flow structure in DC, and the detai...

Context 1
... peak on this record corresponds to the passage of the DW front over the pressure gauge; the time between the peaks is the TDW rotation period Δt. The difference in the magnitude of the pressure in the peaks is due to the internal multifront structure of the TDW (see figure 2) and the discreteness of reading data from the virtual gauge. Structure of rotating detonation wave in detonation chamber with H DC =100 cm, W DC =120cm: normalized density flow field at t=20 ms. Figure 6. ...
Context 2
... Figure 1, we see regular pressure peaks up to about the time moment t=15 ms, which indicates the stability of the CRD regime. The structure of the flow inside the DC at the time t=15 ms is shown in figure 2, the temperature flowfield is presented. Here we see a multifront TDW with a height of about h=25 cm and a classic "triangle" of fresh mixture in front of it. ...

This study describes the experimental characterization of an RDC across a broad parameter range. The operation and stagnation pressure gain of this device are quantified while varying the air injector area, the fuel injector area, the annulus width, the outlet throat area, the mass flow rate, and the equivalence ratio. It is shown that a reduction...
