Description

<p>The just-suspension speed NJS in agitated vessels was estimated by using CFD simulation with the Euler-Euler granular model. Empirical correlations as developed by Zweitering are available for predicting NJS, but the parameter S, which is dependent on the geometry of a tank, is required to estimate NJS from the Zwietering correlation. The just-suspension speeds from both the correlation and CFD were investigated and found to be consistent with each other. The parameter S is often unavailable for a variety of agitated vessels, and just-suspension speeds from experimental measurement and CFD have been found to be adequately consistent for such cases.</p>
