Effect of increasing channel width on the structure of rotating detonation wave

Higher fuel-burn rate and, hence, thrust from a rotating detonation engine (RDE) may be achieved through the use of larger channel widths for the annular tubes in which combustion occurs. However, while it is known that presence of solid walls influences the propagation of a detonation wave in a planar geometry, it is not clear how an increase in channel width would affect the characteristics of a rotating detonation wave in an annular tube. An...
