Aperture radius vs. time. a \(R_{\mathrm{a}}(t)\) vs. time. Thick lines indicate the \(R_{\mathrm{a}}(t)\) of the runs shown in Figs.5, 6, 7, 8, 9 (the thickest pink line indicates the \(R_{\mathrm{a}}(t)\) for Fig. 6). Thin lines indicate runs using suspensions of \(\phi = 0.4\), where we used all runs whose timings of aperture opening could be determined accurately. Ranges of V (\(\text{ cm}^3\)) are as follows ; case 3 : 0.3 - 3; case 4a : 2 - 4; case 4b : 3 - 6; case 5 : 0.6 - 7; case 6a : 10 - 12; case 6b : 10 - 12. b Normalized (\(R_{\mathrm{a}} / R_{\mathrm{b}}\)) version of (a) (see text for details)
