| Research Abstract |
We investigated about flame-wall interaction by numerical simulations and experiments. The wall effects are caused by heat loss and surface reaction. The surface reaction on many common materials may weaken or quench the flames, although those for a catalytic wall can strengthen the flames.
As a numerical result, the quenching distance for the active wall conditions is larger than that for inert wall conditions, and the main reason of "the quenching" is heat loss to the wall, but the surface reaction affect the flame behavior in the immediate vicinity (less than quenching distance) of the wall. Experimental results also show that the difference among wall surface materials can affect distributions of chemical species, but flame properties, such as the flame position and the velocity when flame extinction, do not change when the wall is located in front of or behind the flame.
