Optimization of Electrochemical Flow Capacitor (EFC) design via finite element modeling

Particle Dynamics-Based Stochastic Modeling of Carbon Particle Charging in the Flow Capacitor Systems

“…The charging activity of the particle was maximum near the current collecting boundary. The model also show inactivity of charging in the centers of the flow channels [49,54] in terms of uncha when moving away from the current-collector (CC) boundary. Figure 12 shows the charge distributions in the flow channel for the three geometries.…”

“…where k B is the Boltzmann constant, and T 0 = 273 K is the temperature in Kelvin. The total mass of superparticles was equal to the total mass of spherical carbon particles in the experimental slurry [49,54]. The motion of superparticles was responsible for the physical charge redistribution, which occurred in two ways.…”

“…The model described above is implemented for three specific channel geometries: circular, box-shaped with a linear current collector, and box-shaped with an extended current collector, as shown in Figure 5 [54]. Each geometrical design allows the different direct contact rate between the electrode phase and the CC.…”

“…With the flow channels 5 mm wide and 120 mm long, the contact area for circular flow channel geometry is approximately 1884 mm 2 . The contact area is reduced to 600 mm 2 and 1800 mm 2 for the box-shaped geometry with linear and extended CC, respectively [54]. The circular-shaped channel geometry resembles the prototype used for experimental analysis and later used for the model optimization and sensitivity testing of modeling parameters.…”
