Drying of a liquid droplet suspended in a binary atmosphere
Oberman, Glen J., Farrell, Troy W., Turner, Ian W., & Sizgek, Erden (2006) Drying of a liquid droplet suspended in a binary atmosphere. In Proceeding of the 5th International Conference on CFD in the Process Industries, 13-15 December 2006, Melbourne, Victoria.
In this work, we consider the spray drying of colloidal solutions, as applied to the case of the generation of synroc precursor powders. In this paper, a model of this process is formulated by considering the simplified situation of the evaporation of a pure liquid droplet suspended in a binary atmosphere consisting of the vapour phase of the liquid and an atmospheric gas such as air. Mass, momentum, and energy balances are given for the liquid and gas phases of the problem, and a binary diffusion equation is also given. The subsequent equation set is solved numerically, and the results are compared with experimental data, both of pure droplets, and of sol droplets.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
