The instability and breakup of capillary jets due to propagation of axisymmetrical disturbances is studied numerically. The effects of the velocity profile relaxation and jet contraction are incorporated into the problem in a quasiparallel approximation. The eigenvalue problem obtained for the phase velocity of the disturbances is solved numerically using an initial value technique for boundary value problems. The breakup length L of a liquid jet in air and a liquid jet in another immiscible liquid is computed as a function of the average exit velocity V_0. The L-V_0 curve possesses a maximum and qualitatively describes the jet disintegration in the experimental evidence. The dependence of the jet breakup length on the nozzle length are shown in comparison with the experimental data.
