【 摘 要 】

Raleigh-Taylor (RT) instabilities occur when a low-density fluid attempts to accelerate a high-density fluid. The instability manifests itself by forming bubbles of the low-density that percolate through the high-density fluid. Concurrently, spikes of the high-density fluid 'let' into the low-density fluid. This instability is seen in familiar occurrences such as the growth of icicles and the draining of sinks. If the interface between the two fluids remains perfectly smooth the instability will not occur that is, it must be 'seeded' by a wave-like perturbation. For the two cases mentioned above, a vibration can be sufficient to perform the 'seeding'.
