Droplet Cluster – Analysis, Simulation and Visualization

Abstract

Droplet Cluster -Analysis, Simulation and VisualizationOptical measurements are performed with an inline measurement technique in laboratory and pilot plant columns to obtain information about the droplet swarm at specific locations as a function of process parameters, e.g., time, energy input, and throughput. The column simulation tool LLECMOD was extended to packed and pulsed columns with the possibility of a free choice of the dispersed phase and mass transfer direction. The CFD simulation provides the basis for 3D simulation of hydrodynamics in stirred extraction columns. A one-group population balance model allows a determination of the changing droplet size with little additional CPU time. An enhanced visualization of the column data in 3D space allows fast and targeted analysis of the apparatus behavior.

Quantification of Entrainment Using an Optical Inline Probe

“…The right part contains an area camera (CCD) equipped with a telecentric lens. The OMOP performed well in previous works with different types of apparatuses [19,24,25,27]. The telecentric principle enables a distance-independent imaging of the actual particle sizes without distortion effects.…”

Particle Measurement Techniques in Fluid Process Engineering

“…By combining transmitted light measurement and high‐speed recordings, e.g., it is also possible to precisely observe local phenomena such as coalescence and breakup processes and thus to establish population balances (Fig. ) . This transmitted light method is also able to be adapted to tube flows, bubble columns, and cold‐flow distillation columns from DN 25 to DN 450 , .…”

Particle Measurement Techniques in Fluid Process Engineering

“…In den letzten zwanzig Jahren wurde dieses Thema verstärkt aufgegriffen [5,76] und bspw. Um an den point of interest in industriell relevanten Größenordnungen von Apparaten zu gelangen ist es aber nötig, mit der Optik und Beleuchtung tiefer in den Apparat einzudringen.…”
