Nonlinear theory of flame front instability
A nonlinear, nonstationary equation describing evolution of weakly curved premixed flames with arbitrary gas expansion, subject to the Landau-Dar- rieus instability, is derived. The new equation respects all the conservation laws to be satisfied across the flame front, correctly taking into account influence of vorticity, generated in the flame, on the flame front structure and flame velocity. Analytical solutions of the derived equation are found.
