, Figure 4 shows also numerical results (solid lines) that were obtained using computational fluid dynamics calculations (CFD-ACE ‡ package) using the volume of fluid method. Despite the known weakness of this type of calculation in the vicinity of singularities, the divergence of R agrees rather well with the experimental data
