Characterization of the flame blow-off conditions in a laminar boundary layer with hydrogen injection

Features of flame stabilization in near wall flows

“…In particular, as it was shown in the works of E.P. Volchkov [1] when burning near a flat surface, through which the gaseous fuel was injected, the features of the flow formation played an important role. In the same paper, the regularities of the flame-off conditions were experimentally established, and the model was proposed.…”

“…In a separated flow, unlike a boundary layer on a flat surface, several combustion regimes may be observed. The diagram was obtained for the flame-off condition both for the case of a plane surface and for a surface with an obstacle above it, and a comparison was made with the model proposed by E. Volchkov [1]. This work was supported by the RFBR grant № 15-08-05662а.…”

Analytical Model of the Process of Thermal Barrier Coating by the MO CVD Method

“…As shown in [13], these two chemical processes proceed independently of each other. By writing the balance of diffusion flows on the wall using the atomic fractions of elements, we obtain [22,25] Here, y is the distance normal to the surface. The direction of the flow of reagents will be taken parallel to the surface.…”

“…This work echoes the conclusions of [21] that, according to kinetics studies, at high substrate temperatures, the mass transport is the controlling factor. The authors of [22] consider a 2D boundary layer under conditions where hydrogen fuel mixtures diluted by an inert gas are injected into the air flow through a porous plate upon diffusion combustion. The distance between the reaction front and the wall in the reacting boundary layer is uniquely determined by the composition of the chemical system.…”
