Figure 4
(a–c) Examples of pipes that have been produced using various x, y design parameters (\(\varpi_{x} = \varpi_{y} = 1\)). The dark purple line depicts the growth curve of the pore nucleation points when the pipe is generated using the specified x and y design parameters; the dark purple points are the nucleation points, the lavender points are the vertices of each pore particle determined by the aforementioned equation, the lavender surface is the pore cross-section enclosed by the resulting vertices, and the nearly transparent lavender surface is the pore wall. (a) \(\varpi_{r} = 0\); (b) \(\varpi_{r} = 0.3\); (c) \(\varpi_{r} = 0.6\).
