Fig. 5: Numerical results of concentration in LBC channels.

Based on simulation, the average concentration in each channel of the LBC is calculated. a The concentration within the lab-scale LBC at the experimental conditions: ΔT = 35 K, NaCl aqueous solution at C0 = 210 ppt, concentration profile is fully developed in each channel (\(Q < 0.6\,\,\text{mL}\,\,{\min }^{-1}\)). The first row above the concentration contour plot shows the numerical results of the concentration from each outlet, while the second row is the experimental measured concentration of each outlet. The third row is the relative difference between simulation and experimental results. b The average concentration within a full-scale LBC with 100 × 20 channel pairs under the same experimental conditions as in a. A linear temperature profile was implemented in the simulation. The highest concentration within the LBC is near-saturation C > 250 ppt, while the lowest concentration is around 170 ppt. c The average concentration within a full-scale LBC having the same number of channels as in b. The linear temperature range is RT = 60% and concentration development ratio is RC = 0.78 for the partially developed flow. The ΔT = 35 K, seawater at C0 = 150 ppt. The highest concentration within the LBC is near-saturation C > 250 ppt, while the lowest concentration is around 80 ppt.
