dc.description.abstract | A temporal analysis of the evolution of Gaussian wave packets in cylindrical capillary jets is presented
through both a linear two-mode formulation and a one-dimensional nonlinear numerical scheme. These analyses
are normally applicable to arbitrary initial conditions but our study focuses on pure-impulsive ones. Linear
and nonlinear findings give consistent results in the stages for which the linear theory is valid. The inverse
Fourier transforms representing the formal linear solution for the jet shape is both numerically evaluated
and approximated by closed formulas. After a transient, these formulas predict an almost Gaussian-shape
deformation with (i) a progressive drift of the carrier wave number to that given by the maximum of the
Rayleigh dispersion relation, (ii) a progressive increase of its bell width, and (iii) a quasiexponential growth
of its amplitude. These parameters agree with those extracted from the fittings of Gaussian wave packets to
the numerical simulations. Experimental results are also reported on near-Gaussian pulses perturbing the exit
velocity of a 2-mm diameter water jet. The possibility of controlling the breakup location along the jet and other
features, such as pinch-off simultaneity, are demonstrated. | es |
