Use of a-shapes for the measurement of 3D bubbles in fluidized beds from two-fluid model simulations 2016 Access copy available to the general public Unrestricted A geometrical technique based on shape construction was employed to reconstruct the simulated domain of 3D bubbles in a gas-solid fluidized bed, from two-fluid model (TFM) simulations. The Delaunay triangulation of the cloud of points that represent volume fraction iso-surfaces in transient TFM simulations was filtered by means of the so-called a-shapes, allowing a topologically accurate description of 3D bubbles within a fluidized bed. Consequently, individual 3D bubble properties such as size and velocity were measured. Simulated bubble characteristics were further compared to those measured on pseudo-2D bed facilities by image techniques in order to illustrate the effect of the bed geometry on the bubbling behavior under mimicked operational conditions. info:eu-repo/grantAgreement/ES/MINECO/ENE2013-44350-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.942 2016 ENGINEERING, CHEMICAL 30 / 135 = 0.222 2016 Q1 T1 0.974 2016 Chemical Engineering (miscellaneous) 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-3003-5856 González, D.
