摘要：

The η model in the linear or radial geometry is investigated numerically. It turns out that the main characteristics of the viscous fingering instability (η=1) at vanishing capillary number such as the λ=1/2 limit are not recovered. For η 1, the selected finger width decreases with the capillary parameter, indicating the formation of needlelike structures. © 1995 The American Physical Society.
