Figure 5 | n_and_phi_inertial_axes.pdf | Density (colour-map) and potential (contours; solid for phi>0, dashed for phi<0) for a filament in the inertial regime, at maximum V_{x} | 0 | CF/15/80 | Download | ||

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 | ||

Figure 9 | 3d_compare.pdf | Comparison of 2D (lines) and 3D (markers) results for A=2 and several epsilon | 1 | CF/15/117 | Download | ||

Figure A1 | delta_MAST-parameters.pdf | Scaling for circular filaments with amplitude A=4 and using MAST relevant dissipative parameters | 0 | CF/15/119 | 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}.
