Abstract
This paper is a report on using a liquid jet to generate spherical lithium granules which can be used in fusion devices. The liquid jet uses liquid lithium as the continuous phase and liquid paraffin as the dispersed phase which can effectively prevent the lithium granule from oxidation and carbonization considering the active chemical property of lithium. The liquid lithium flows through a nozzle and breaks up into globules that have diverse diameters. A deeper investigation indicates that the temperature and pressure difference, which directly influence the flow velocity, have impacts on the distribution of granule size. The increases of temperature and pressure result in the granule size approaches the orifice diameter. Thus, suggesting a method to generate small spherical lithium granules that are controllable in size by adjusting the orifice size, temperature and pressure difference.
