Stretched laminar diffusion flames
Laminar diffusion flame

Stretched laminar flames, both premixing and diffusion, have been and still are the subject of numerous studies, both theoretical and experimental. The simplest configuration for a diffusion flame is the counter-current flame (figure 15 ). A jet of fuel and a jet of oxidizer in opposite directions form a flow with a stagnation point (x = y = 0). The flame front is then drawn in its own plane, close to the y = 0 plane. The interest of these stretched flames is twofold.

• This is one of the simplest configurations. To a first approximation, these flames can be assumed to be one-dimensional, depending...
