| Abstract: | The eff ect of single mode initial conditions at the interface of Rayleigh-Taylor(RT) mixing are experimentally examined utilizing the low Atwood number water channel facility at Texas A&M. The water channel convects two separated strati ed flows and uni es them at the end of a splitter plate. The RT instability is attained by convecting a cold stream above a warmer stream. Average density calculations are based on long time average optical measurements. The water channel was modifi ed with a flapper n like device at the end of the splitter plate which was actuated by a computer controlled servo motor. Other modi fications to the experiment were implemented resulting in reduced uncertainty. The experiment examined fi ve diff erent modes in addition to the baseline: 2 cm, 3 cm, 4 cm, 6 cm, and 8 cm wavelengths. The mixing width growth rates were shown to be dependent on initial conditions. Additionally, it appears that the growth rates commence with terminal velocity and are observed to line up with the baseline case. |
