ANNIHILATIVE FRACTALS FORMED INrnRAYLEIGH-TAYLOR INSTABILITY

摘要

We report on a fractal pattern formed in Rayleight-Taylor instability. The fractal dimension is 1.88 ± 0.06, which is constant in time t > t1 = 70 s. The pattern area decreases according to exp(-t/τ), where t and τ are time and time constant 69.8 s, respectively. τ agrees with t1. This result leads that it is important for the fractal formation that sufficient annihilation of the heavier solution at the surface.
