Abstract
Based on the linear analysis of stability, a dispersion equation is deduced which delineates the evolution of a general 3dimensional disturbance on the free surface of an incompressible viscous liquid jet injected into a gas with swirl. Here, the dimensionless parameter J(e) isagain introduced, in the meantime, another dimensionlessparameter E called as circulation is also introduced to represent the relative swirling intensity. With respect to the spatial growing disturbance mode,the numerical results obtained from solving the dispersion equation reveal the following facts. First, at the same value of E, in pacewiththe changing of J(e), the variation of disturbance and the critical disturbance mode still keep the same characters. Second, the present results are the same as that of S.P. Lin when J(e) > 1; but in the rangeof J(e) < 1, it's no more the case, the swirl decreases the axisymmetric disturbance, yet increases the asymmetric disturbance, furthermorethe swirl may make the character of the most unstable disturbance mode changed (axisymmetric or asymmetric); the above action of the swirl becomes much Stronger when J(e) << 1.
