• 論文の詳細を見る

• 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 examine 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 rings into a single ring at an early stage of interaction, but also the process of splitting the single ring into two rings at the following stage was reasonably simulated by the modified model.
