dc.description.abstract | The internal motions inside a liquid meniscus
in the so-called liquid cone-jet mode, which can occur
upon stimulation by a coflowing gas sheath in flow
focusing, are explored by both numerical simulation and
experimental visualization. The results for low viscosity
liquids show that, as in previous numerical simulations, a
recirculating cell inside the meniscus appears when the
injected liquid flow rate is reduced. Thus, as the flow rate is
reduced not only the average residence time of particles in
the meniscus becomes longer, but the appearance of a
recirculation cell provides a natural platform for the efficient micro-mixing of different species before they are
ejected through the issuing jet. The numerical results were
confirmed with experimental visualization of the flow
inside the meniscus using a dyed liquid. However, when
the viscosity of the liquid is increased the recirculating cell
disappears. In this case, viscous stresses organize the
streamlines and direct the flow to the meniscus tip, which
prevents the recirculating cell from being formed even for
very small injected rate of liquid flow. | es |
