dc.description.abstract | A novel swirl flow-focusing microfluidic axisymmetric device for the generation of monodisperse microbubbles at high production
rates to be used as in-line contrast agents for medical applications is presented. The swirl effect is induced upstream
of the discharge orifice by a circular array of microblades which form a given angle with the radial direction. The induced
vortical component on the focusing liquid stabilizes the gas meniscus by the vorticity amplification due to vortex stretching
as the liquid is forced through the discharge orifice. The stabilized meniscus tapers into a steady gas ligament that breaks
into monodisperse microbubbles. A reduction up to 57% in the microbubble diameter is accomplished when compared to
conventional axisymmetric flow-focusing microdevices. An exhaustive experimental study is performed for various blade
angles and numerous gas to liquid flow rate ratios, validating previous VoF numerical simulations. The microbubbles issued
from the stabilized menisci verify prior scaling law of flow-focusing. | es |
