Rotating Detonation Combustors are studied with increasing interest worldwide, and are seen as the most promising of the available pressure gain (stagnation) combustion concepts. The dynamics and structure of rotating detonations are an area of active interest owing to their sensitivity to a wide range of factors, which have been hard to predict. In the current manuscript, we argue that rotating detonations share a considerable number of quantitative and qualitative properties with spinning detonations, which is a well-known near-limit phenomenon in fundamental detonation studies. We show that the fill height in rotating detonations play the same role as the pitch length inscribed by spinning detonations. While the pitch-to-hydraulic diameter ratio of spinning detonations is known to range from 2 to 6 across a wide range of conditions, it is shown here, from literature, that the fill height-to-hydraulic diameter of rotating detonations also extends across a similar range—between 1 and 5 across diverse facilities and conditions.
