Figure Legend:
Geometry and pressure field of optimized surface textures with spline design representation (spline resolution N = 5). Asymmetry is permitted. Six designs are uniformly sampled from 27 designs in the Pareto set to illustrate trends. (a)–(f) Geometric texture profile level sets and (g)–(l) pressure field level sets. Note that these Pareto-optimal designs are located in Fig. 14 (square symbols). (a) and (g) design #4 (FN = 0.750 N, ηa/η0 = 0.299), (b) and (h) design #8 (FN = 1.750 N, ηa/η0 = 0.394), (c) and (i) design #12 (FN = 2.750 N, ηa/η0 = 0.469), (d) and (j) design #16 (FN = 3.753 N, ηa/η0 = 0.538), (e) and (k) design #20 (FN = 4.750 N, ηa/η0 = 0.607), (f) and (l) design #24 (FN = 5.752 N, ηa/η0 = 0.709).
