Abstract
A method of stabilizing a strained flame in a stagnation flow reactor. By causing a highly strained flame to be divided into a large number of equal size segments it is possible to stablize a highly strained flame that is on the verge of extinction, thereby providing for higher film growth rates. The flame stabilizer is an annular ring mounted coaxially and coplanar with the substrate upon which the film is growing and having a number of vertical pillars mounted on the top surface, thereby increasing the number of azimuthal nodes into which the flame is divided and preserving an axisymmetric structure necessary for stability.
Claims10
A device for stabilizing highly strained flames, comprising:
- a) a reactor including a means for admitting a gas to said reactor, wherein the gas is capable of forming a flame for growing a film and a substrate suitable for growing the film thereon;
- b) an annular ring having a top surface and positioned coaxially and coplanar with the substrate;
- and
- c) spaced apart, vertical pillars mounted on the top surface of said annular ring, wherein said pillars are spaced equidistant from one another thereby dividing the flame into equal segments.
