S. Kawano et al., SEQUENTIAL PRODUCTION OF MM-SIZED SPHERICAL-SHELLS IN LIQUID-LIQUID GAS SYSTEMS, Journal of fluids engineering, 118(3), 1996, pp. 614-618
A new device has been developed for sequential production of mm-sized
solid spherical shells ruing liquid-liquid gas systems. This device co
mprises a cylindrical vessel, for containing two kinds of immiscible l
iquids, and a gas injection orifice, set at the center of the vessel's
bottom. Solid spherical shells are successfully and sequentially prod
uced by solidifying rising liquid spherical shells, formed sequentiall
y at the horizontal interface between two immiscible liquids.
