SRDC end of project final report JCU010 Mathematical modelling of circulation and crystallisation in vacuum pans
MetadataShow full item record
1. Survey Australian sugar mills to determine details of vacuum pans in current use. Information to be sourced includes the type of vacuum pans, whether batch or continuous pans are used and whether or not mechanical stirrers are employed. 2. Analyse the flow and heat transfer in calandria tubes using a two-phase (vapour/massecuite) Eulerian/Eulerian CFD model. Compare results with published experimental data. 3. Construct a numerical model of the overall flow field and temperature field in a typical high grade vacuum pan with natural circulation. 4. Investigate the effect of adding a mechanical stirrer on the circulation patterns, heat transfer and crystallisation process. 5. Propose modifications to the geometry and/or operation of stirred and unstirred vacuum pans that will improve the circulation patterns and the crystal growth.
