Figure 4 n_and_phi_sheath_axes.pdf Density (colour-map) and potential (contours; solid for phi>0, dashed for phi<0) for a filament in the sheath regime, at maximum V_{x} 1 CF/15/81 Download
Figure 7 deltaz-deltax_A4.0.pdf Inertial scaling vs. delta_{x} (left) and sheath current scaling vs. delta_{z} (right) for several values of epsilon and alpha 0 CF/15/91 Download
Figure 8 amplitude_fig.tar.bz Amplitude scaling in the inertial regime, delta_{x}=delta_{z}=0.5, (left) and in the sheath current regime, delta_{x}=delta_{z}=200, (right). The solid red line shows the fitted linear ansatz, [eq:ansatz_lin], and the dashed black line shows the fitted square-root ansatz, [eq:ansatz_sqrt] 0 CF/15/92 Download

Table B1 Inertial amplitude scaling Inertial regime: Comparison of (i) values of beta inferred by least squares regression on the relative error between the ansatz [eq:ansatz_sqrt] (square-root scaling) and filament velocities measured from simulations and (ii) ratio of residual for this regression to that for regression with the ansatz [eq:ansatz_lin] (linear scaling), at delta_{x}=0.5 for several values of delta_{z}. Amplitudes used for the analysis were A=1,1.5,2,3,4,5,6,7,8. For extreme values of ellipticity the filament is no longer in the pure inertial regime. Both viscous and sheath current regimes have linear scaling, so the square-root fit is then less good. 0 CF/15/120 Download
Table B2 Sheath current amplitude scaling Sheath current regime: Comparison of (i) values of beta inferred by least squares regression on the relative error between the ansatz [eq:ansatz_lin] (linear scaling) and filament velocities measured from simulations and (ii) ratio of residual for this regression to that for regression with the ansatz [eq:ansatz_sqrt] (square-root scaling), at delta_{z}=200 for several values of delta_{x}.
