it is still less than 10

coarse particles. It is also noted that for

flame is stable and its height is
considerably reduced. This can be an added advantage, as reduced
U p
2, the
fl
flame heights
help to reduce the combustor length, the amount of material used for the combustor,
its manufacturing cost, and most importantly, the weight of the combustor. This
would prove to be extremely useful when considered from the point of view of
aircrafts. The combustor temperatures observed are also not that high for
fl
U p
2.
This implies that a combustor used with such a burner con
guration need not be
made of a highly heat resistant material, which again implies a reduction in the
manufacturing cost for an aircraft engine. The study reported here establishes the
fact that the quality of combustion and the emissions can be improved considerable
by partially premixing the fuel. However, there is a critical limit of premixing
beyond which not much improved is gained in terms of the combustor performance.
