Abstract
The vortex blob model, which is one of the previously proposed vortex models in the vortex method, was modified to correctly take account of the viscous effect with a simpler procedure of calculation. To examin e the usefulness of the modified model, the interaction of two vortex rings is calculated with it and two other vortex models, the filament model and the vorton model. As a result of the comparative calculation , it was confirmed that not only the process of connecting the two rin gs into a single ring at an early stage of interaction, but also the p rocess of splitting the single ring into two rings at the following st age was reasonably simulated by the modified model.
