The two-dimensional and axially symmetrical supersonic jets of an ideal dissociating gas with finite reaction rate are considered on the basis of the linearized theory. Basing on the fact that δ≡(Me2−Mf2)⁄(Mf2−1) (Mf and Me denote respectively the frozen and equilibrium Mach numbers) is always sufficiently small, an approximate method of analysis is developed. Changes of the shape and the axial velocity distribution of the jet due to variations of the parameter δ and the reaction rate are investigated in detail. Owing to the finite reaction rate, the jet has the wavy configuration damping toward downstream and tends to the equilibrium, uniform flow at infinity downstream. According as the reaction rate changes from zero to infinity, the possible transition of the jet structure from the inert to the equilibrium limit can be found.
