National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Production of a raleigh-taylor instability target.

DE2001768255

Publication Date	2000
Personal Author	Day, R.
Page Count	6
Abstract	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 jet 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.'
