The prediction of particle cluster properties in the near wall region of a vertical riser (200157)

Correlations for predicting the properties of clusters of particles travelling near the riser wall are presented. The correlations were developed from experimental data published in the literature on vertical risers ranging from laboratory to industrial scale. Expressions are presented for predicting the size, shape, density, wall film coverage and velocity of particle clusters. These expressions should prove useful in the development of heat transfer and process models for gas-solid riser flow. (C) 2002 Elsevier Science B.V. All rights reserved.
