Mean flow speed U z at zero adverse pressure (left) and d p /d z = 1 Pa μm −1 (right). In the absence of adverse pressure, systems with small h / H and large H produce the fastest flows. Under adverse pressure, the maximum speed occurs at a larger h / H and smaller H . Dashed lines in f and g show the contour shape of the respective colour maps. Parameter values were set as follows: H = 10 μm in b – d with the light grey backgrounds indicating the ciliary layers. φ c = 0.1 in b – d . In f and g , φ c follows from the smooth fit of e . κ / μ = 1 μm −2 in c – g , f / μ = 1 s μm −1 in c and d , f = 15 pN μm −3 in g and μ = 10 −3 Pa s throughout.
