 note = {A brief report is made on the recent analysis on the recombination of two vortex filaments in a viscous incompressible fluid. The analysis is confined to a local flow field where this interaction occurs, and is based on the vorticity equation with the viscous term along with several assumptions, including fluid impulse conservation and spatial symmetry of the flow field. The flow field is expanded into polynomials of coordinates and the coefficient, which are functions of time, are obtained by substituting the expansions into the vorticity equation. It is proved that this process is completed within a short time t*=0(σ^2/Г), where σ and Г are the size and the circulation of the vortex filaments respectively, and that the viscous effect is necessary for occurrence of the process., 資料番号: SA0033528000},
