FLAME PHENOMENA (Propagation, ignition in a gas)
2-dimensional (x-y), cartesian, steady, elliptic simulation
Demonstration of some steady one-phase flame phenomena
namely :- 1 D spontaneous ignition in a long duct
1 D laminar flame propagation
----------------------------------------------------
r=1.e-4 <--| flame-front r=1.
-----------------------------------------------------
x----->
In order to enable parametric studies to be made quickly,
and to facilitate display, each problem is made 2 D,
the additional dimensions being used for the varied
parameters.
