【Abstract】 A linear analysis has been carried out for the instability of an annular swirling inviscid liquid jet moving into a quiescent inviscid gas medium. The results show that the quasi-sinuous mode disturbance is predominant for the instability of the annular swirling liquid jet. The effects of a number of non-dimensional parameters, including the Weber Number, the density ratio of gas and liquid, the ratio of inner and outer radii, the swirl number, on the instability of the jet have also been studied considerably.更多还原
