Hybrid LES–multizonal modelling of the uranium oxalate precipitation

摘要: Abstract Oxalic precipitation is usually applied to process radioactive wastes or recover actinides from a multicomponent solution. Due their later handling and use, actinide precipitates have satisfy strict requirements. In nuclear environment where experiments are limited, simulation may be the only way test different industrial configurations in order adjust campaigns. this manuscript, modelling of tetravalent uranium oxalate an unbaffled reactor achieved using hybrid multizonal/CFD model. The population balance solved according moment method multizonal model entirely parameterised through computational fluid dynamics calculations based on large-eddy (LES) sub-grid micromixing. show how specificity flow field can noticeable effect properties.
