Abstract

We have qualitatively and quantitatively analyzed the labyrinthine instability of an immiscible droplet under a perpendicular field. Interesting reverse-growing fingers are recorded for the situation with an extremely vigorous fingering instability. The experiments further confirm the strong correlation between the fastest growing mode by theoretical predictions and the final number of fingers within a wide range of modes. Also validated is the dependence of a critical magnetic Bond number for the 2-lobe mode on the dimensionless diameter. Verifications of the theoretical results have given more reliable supports to the correctness of the applied mathematical model and the following up simulations based on the model.
