“…3 International Journal of Photoenergy term of turbulent diffusivity that appears in (5). This term is associated to jet flows, eddies, and local flow deviations caused by the inherent turbulent flow inside the system [31,32]. Worthy of mentioning, we performed several simulations including the turbulent diffusivity coefficient (not shown herein) in order to develop a more rigorous model.…”

This paper deals with the analysis and interpretation of flow visualization and residence time distribution (RTD) in a compound parabolic concentrator (CPC) reactor using computational fluid dynamics (CFD). CFD was calculated under turbulent flow conditions solving the Reynolds averaged Navier–Stokes (RANS) equation expressed in terms of turbulent viscosity and the standard k−ε turbulent model in 3D. A 3D diffusion-convection model was implemented in the CPC reactor to determine the RTD. The fluid flow visualization and RTD were validated with experimental results. The CFD showed that the magnitude of the velocity field remains almost uniform in most of the bulk reactor, although near and inside the 90° connectors and the union segments, the velocity presented low- and high-speed zones. Comparisons of theoretical and experimental RTD curves showed that the k−ε model is appropriate to simulate the nonideal flow inside the CPC reactor under turbulent flow conditions.

“…In addition to experimental tracer measurements, RTDs can also be determined from detailed spatial flow field distributions obtained using CFD simulations. For example, Zou et al and Kalaga determined the solid residence time distributions in multicompartment and multistage fluidized beds, respectively, and Cruz-Díaz et al compared experimental and simulated residence time distribution curves from a filter-press electrochemical reactor. Generally, good agreement was achieved between RTD curves obtained experimentally and using CFD.…”

Open-cell foams are a promising alternative for the separation of liquid droplets suspended in gas flows at comparably low pressure drops. Separation in such ceramic foams is investigated using the residence time distribution of droplets derived from pore-scale CFD simulations. Silicon-infiltrated silicon carbide (SiSiC) open-cell foam samples (20 and 45 pores per inch, ppi) are considered. The foam structure was reconstructed from microcomputed tomography (μCT) images. To track the droplets, a Lagrangian discrete-phase model was used. The effects of pore size and pore density on the droplet retention time were studied. The flow pressure drop showed remarkable agreement with the in-house experimental measurements. The droplet separation efficiency within the foam structure was found to generally increase with the inlet gas velocity and the droplet inertia.

“…The commercial cells in studies about wastewater treatment have been designed for other applications (typically electrosynthesis); therefore, special considerations of wastewater treatment are sometimes disregarded. Three relevant cells are typically discussed in studies about the electrolysis of wastewater: the ElectroCell (ElectroCell A/S, Denmark), the FC01‐LC (formerly ICI Chemicals and Polymers Ltd.; currently INEOS Chlor‐chemicals, UK) and the DIACELL (formerly ADAMANT TECH; currently WaterDiam, Switzerland) . The first two cells were designed for the chlor‐alkali process and have to be adapted (or at least applied in different conditions) for application in studies about wastewater treatment.…”

BACKGROUND In recent years, the application of electrochemical wastewater treatment processes has proven to be very efficient in the removal of recalcitrant organic compounds. However, the scale‐up of the boron‐doped diamond (BDD) anode system for industrial applications has not been sufficiently evaluated. This study assesses the effect of increasing the number of compartments in the same electrochemical module (DiaCell® 1001) on the treatment of synthetic wastewater with pesticide 2,4‐D and chlorides. This commercial module can be considered to be a stack of cells, in which the number of single cells varies from 2–10 and the anode areas range from 140–700 cm−2. RESULTS The results of the study demonstrate that an increase in the number of cells and a decrease in the resulting current density at the same current intensity caused an increase in the removal and mineralisation rates. Complete mineralisation was attained in all configurations tested. The production of hazardous species, such as chlorates and perchlorates, are also affected by the number of stacked cells, which causes them to be positioned lower in the stack due to the large number of cells. CONCLUSIONS No distinct differences in electrochemical efficiency are observed among the different configurations tested. However, a distinct improvement in the energy efficiency (g kWh−1) with an increase in the number of stacked cells is observed due to the reduced stack potential caused by applying the same current intensity to the stack with the higher number of cells. © 2015 Society of Chemical Industry
