Stability of Pole Solutions for Planar Propagating Flames: I. Exact Eigenvalues and Eigenfunctions


It is well known that the nonlinear PDE describing the dynamics of a hydrodynamically unstable planar flame front admits exact pole solutions as equilibrium states. Such a solution corresponds to a steadily propagating cusp-like structure commonly observed in experiments. In this work we investigate the linear stability of these equilibrium states—the… (More)
