概要

• 論文の詳細を見る

• A new fractal dimension of diffusion-limited aggregation (DLA) is studied by tip front angle near hottest branch projecting bare field, which is obtained from envelope line considering near pentagonal symmetry of DLA. The angle changes largely along cluster growth, and the mean shows 106.2° for 10^5 N=3×10^6 clusters. From application of wedge model, tip front dimension is obtained as D_t=1.709. Asymptotic fractal dimension D_t=1.710 can be estimated consistently with usual box and gyration dimensions from 25 N=2×10^8 clusters.
