BENDING OF A VISCOUS JET EMANATING FROM A CAPILLARY

The bending of the jet of a viscous fl uid, outfl owing from a capillary, under the joint action of the inertial, viscous, and surface tension forces of the fl uid in it, was investigated. A linear model of the bending of such a jet is proposed. The dispersion relations have been obtained for the rate of increasing the disturbances of this jet. It is shown that the jet bends spontaneously. A qualitative analysis of the infl uence of the viscosity of a fl uid and the velocity of its outfl ow from a capillary on the angle of deviation of the fl uid jet formed from the capillary axis has been performed.
