In this project, we study the production of viscoelastic jets with gaseous flow focusing and its applications. The rheological nature of the liquid alters the focusing phenomenon in several important aspects. Long filaments with Weber numbers on the order of 10−4 are produced. Elastic stresses inhibit the jet break-up beyond the discharge orifice.
These properties confer this technique on a great potential in the production of special fibers and in 2D/3D printing, both for industrial or biomedical applications.
