摘要：

As a hydrodynamic analog of dendritic crystal growth, we have performed viscous fingering experiments under the influence of linear anisotropy through a straight groove. A single finger on the groove always tends to grow faster, accompanied by side branches. It is found that (1) the finger tip profile is approximated by a parabola, (2) the finger tip speed v and the radius ρ satisfies the relation vρ2 = constant for a wide range of v, and (3) the side branch spacing λ is approximately proportional to ρ. The crossover behavior to the constant ρ is also found for larger values of v in the v-ρ relation. © 1990.
