The laws of conservation of momentum, energy, and angular momentum fluxes during capillary disintegration of a rotating jet

On the basis of the energy and momentum conservation laws for the process o f disintegration of a rotating cylindrical jet as a capillary continuum, ri gorous and outstandingly simple universal equations of disintegration al e derived. The Bernoulli equation for a steady-state "stream tube" is shown t o have the same form for jet disintegration as well. The effect of capillar y-centrifugal self-retardation of a disintegrating jet is revealed, as well as the effect of the drop in its internal energy, which takes place in the process. The seemingly paradoxical relationship between these effects is e stablished; they are proved to be completely independent of the surface al ea formed during disintegration under the conditions of fixed parameters of the initial unperturbed jet. The law of conservation of the angular moment um flux during disintegration of a rotating jet is mathematically formulate d and studied.
