E. Balakrishnan et al., PATH-FOLLOWING FOR DISJOINT BIFURCATION PROBLEMS ARISING IN IGNITION THEORY, Mathematical and computer modelling, 19(9), 1994, pp. 9-15
The correct formulation governing the ignition of a solid reactant und
ergoing slow oxidation gives rise to a nonlinear problem which in symm
etrical geometries (infinite slab, cylinder, and sphere) is a two poin
t boundary value problem. The discontinuity in the smallest branch of
steady-states is the threshold for ignition. The solution branches are
found by modifications of the path-following software (AUTO). Gross m
ultiplicity of steady-states occurs for dimensions greater than two, a
nd in all cases, the diagrams exhibit ''disjointedness'' for some para
meter values which require special redefinition of the nonlinearity.
