“…A 3D model was presented by Gesit et al [21] for predicting the flow patterns and hydraulics of the sieve tray by a CFD device, utilizing the association of Colwell [22] for the liquid holdup working well in the force direction. A 3D CFD simulation was presented by Teleken et al [23][24][25] with the mathematical homogeneous biphasic model, for evaluating the effect of the electrical resistance of heaters over the sieve tray surfaces and its hydrodynamics. Moreover, Teleken et al [23][24][25] assessed the flow of a falling liquid film in a distillation column via an Eulerian-Eulerian CFD technique.…”

The weeping phenomenon was investigated using some experimental tests and a numerical model. The tests were performed within a 1.22‐m‐diameter pilot‐scale column including two chimney trays and two Nye test trays with an air‐water system. The rates of weeping were measured in the Nye trays with two heights of the weir and a hole area of 5 %. Moreover, the weeping rates in the outlet and inlet halves of the Nye tray and the total weeping rate were calculated. In the next step, an Eulerian‐Eulerian computational fluid dynamics (CFD) technique was used. The results show good agreement between the attained CFD findings and the experimental data.

A new and extended version of a generic modeling framework for analysis and design of crystallization operations is presented. The new features of this framework are described, with focus on development, implementation, identification, and analysis of crystallization kinetic models. Issues related to the modeling of various kinetic phenomena like nucleation, growth, agglomeration, and breakage are discussed in terms of model forms, model parameters, their availability and/or estimation, and their selection and application for specific crystallization operational scenarios under study. The advantages of employing a well-structured model library for storage, use/reuse, and analysis of the kinetic models are highlighted. Examples illustrating the application of the modeling framework for kinetic model discrimination related to simulation of specific crystallization scenarios and for kinetic model parameter estimation are presented.
