BREAK-UP OF A LIQUID JET - 2ND PERTURBATION SOLUTION FOR ONE-DIMENSIONAL COSSERAT THEORY

The second perturbation solution is derived within the nonlinear one-dimensional Cosserat theory for a liquid jet emanating from a nozzle with harmonic excitation. Numerical results are presented for parameters relevant to ink-jet printing technology. Satellite drops are predicted but always in the backward merging condition. The results are compared with the corresponding solution obtained by W. T. Pimbley and H. C. Lee, who used a different one-dimensional set of equations with a different formulation of the problem and obtained forward merging satellite drops under some conditions.
