a \({\rm{SEC}}\) when varying the split ratio and ST. Split ratio is varied between 0.3 and 1 (the latter being a perfect top–bottom flow split at each channel outlet), and the absolute value of ST is varied from 10−3 K−1 to 10 × 10−3 K−1. The previous simulations assuming “perfect split” for seawater and other concentrates in Fig. 6 are labelled. The vertical lines are ST of 2.40 × 10−3 K−1, 2.50 × 10−3 K−1, 3.61 × 10−3 K−1, and 10.00 × 10−3 K−1, corresponding to seawater brine, LiI, K2SO4, and NaOH aqueous solutions, respectively. b \({\rm{SEC}}\) as a function of the split ratio for four values of ST, representing the types of feed indicated in the legend. c Yield flow rate per unit channel area (Q/A) per day when varying split ratio and ST. D(25 °C) = 1.35 × 10−9 m2 s−1 was used, which is approximately the D of K2SO4. d Q/A is plotted for different D and split ratio is 0.7. Different concentrates are labelled.
