Аннотация:A nonlinear equation describing curved stationary flames with arbitrary gas expansion θ = ρfuel/ρburnt is obtained in a closed form without an assumption of weak nonlinearity. The equation respects all conservation laws and takes into account vorticity production in the flame. In the scope of the asymptotic expansion for θ→1, the new equation solves the problem of stationary flame propagation with accuracy of the sixth order in θ-1. Its analytical solutions give the flame velocity in tubes of arbitrary width, which agrees with available results of direct numerical modeling.
