Particulate flow model solution

Emulsion phase in completely mixed state General solution—bubble phase free of solids (Orcutt model) In the following, the simplified Orcutt-Davidson-Pigford model (Orcutt et al., 1962) is presented. This model assumes in addition that the bubble phase is free of solids, and thus yh = 0. This means that the reaction takes place only in the emulsion (dense) phase. Then, the third term in eq. (3.516) disappears. The gas flow is in the inlet of the bed ,A, the particulate phase wfmA, and the bubble phase wswfmA, where A is the cross-sectional area of the bed and (eq. 3.476)... 

At NIC, as a contribution to subproject AEROSOL, EUROTRAC-2, laboratory experiments with a continuous flow of some trace gases under controlled conditions, were performed in a reactor chamber. The preliminary results of SO2 oxidation in synthetic solutions containing various catalytically active metal ions were discussed. A laboratory model study of the role of aerosols composition in the process of formation of seeondary acidie speeies from gaseous and particulate precursors was performed. 

Figure 14.4 Nebulizers. Models cross flow (1), concentric (2) and parallel (3). In contrast to models 1 and 2, model 3 is not subject to particulate obstruction by impurities in the solution. They leave through a large capillary that drains hy gravity along a V-groove design to the outlet where the aerosol is produced (Babmgton nehulizer). For the solution, a pump regulates the flow of the aerosol. The chamber at the outlet of the nehulizer is used as a drain to eliminate the larger droplets hy gravity.
