The decrease in laminar burning rates for p ⩾ 8 bar led to a push of the gaseous reaction zone close to the channel wall, to a subsequent leakage of hydrogen through the gaseous reaction zone, and finally to catalytic conversion of the escaped fuel at the channel walls.
Radical heterogeneous reactions promoted mildly the onset of homogeneous ignition at p ⩾ 2 bar due to the net desorptive flux of OH over the gaseous induction zone.
The decrease in laminar mass burning rates at p > 4 bar led to a push of the gaseous combustion zone close to the channel wall, to leakage of H2 and CO through the flame and, finally, to subsequent catalytic conversion of the leaked fuel components.
Laboratory column experiments were conducted by employing various porous media to delineate the characteristics of gaseous ozone transport in the unsaturated zone under various conditions.
However, in practice, before the tube is placed into the liquid nitrogen, it passes through a space containing gaseous nitrogen (pre-cooling zone) formed via the evaporation of the bulk liquid nitrogen.
The experimental configuration was that of a rearward-facing step with distributed injection of gaseous fuel into the recirculation zone.
The heat transfer from the catalytic surface to the gaseous mixture in the catalytic zone exhibited a high intensity under the large flow velocity, and the preheated incoming flow improved the heterogeneous reaction to inhibit the homogeneous reaction.
The triggered detonation is the result of interaction of the multiple waves, more accurately, is a direct result of the re-ignition in the gaseous explosive in the unreacted zone by the reaction-released energy that is transferred in the form of the characteristic wave.
Special features of the experimental arrangement used included the relative thinness of the boundary layer of the separating air stream and the distributed nature of the gaseous fuel injection into the recirculation zone.
The analysis is focused on the uniformity of gaseous and surface concentrations in the catalyst zone, which is a key property of TZTR model.
