Extractions: Sonoluminescence is the process by which sound waves are utilized to resonate an air bubble suspended in a medium with the resulting oscillations causing cavitation of the bubble wall producing an emission of visible light. Here, the effects of varying the medium were researched and analyzed by the Rayleigh-Plesset equation and parametric instability. Distilled water was used as a control and trials were run with salt (NaCI) and Glycerin (CH OHCHOHCH OH) solutions in water castor and olive oil, methyl alcohol and Potassium Chloride (KCl) solutions. It was found that the non-aqueous mediums were not suitable for Sonoluminescence, while the glycerin increased the bubble's stability. The salt solutions were inadequate but the potassium chloride trials demonstrated that solid state solutes did not inhibit Sonoluminescence. No suitable mediums were found for X-ray analysis. In the late 1980's the resurgence of interest in SL (abbreviation for Sonoluminescence) generated a race to deduce the cause and intensity of the produced light. Chemists Kenneth Suslick and Edward Flint made light-emitting vapor bubbles by sending ultrasonic waves through liquid hydrocarbons such as dodecane. By examining the spectrum of the released light they showed that the vapor reached temperatures up to 5000 degrees Celsius. Suslick, along with Doktycz also created particle collisions with this method. They caused through acoustic cavitation particles of zinc powder to melt together. (2,3)

Sonoluminescence Overview And Future Applications

http://www.redesignz.fsnet.co.uk/sonolexp.htm

Extractions: Updated on 1/20/96 note: there are broken links on this page Back The brilliant blue glow in the picture above is one of many examples of sonoluminescence. The scientific-sounding word basically translates to "sound into light." The idea is very simplea small bubble, surrounded by some liquid, is bombarded with sound. Due to the high energies now in the bubble, it starts to luminesce, or produce light. When researchers first discovered this phenomenon, they called it sonoluminescence While sonoluminescence was first discovered in the 1930's, it received little attention until recently. In the past few years, a number of discoveries have been made, opening up even more mysteries. While most people have heard nothing about sonoluminescence, it has great potential in many scientific areas. High on the list for many researchers is its applications to fusion , since it is predicted that as sound bombards a bubble, the temperatures can get so hot as to allow fusion to occur within the bubble. Accordingly, there is some exciting research going on in this new field, and, according to

Extractions: N ew studies of the phenomenon of sonoluminescence, as well as industrial and medical applications of shock wave physics, were among the highlights of the biennial international meeting of the APS Shock Compression of Condensed Matter Topical Group, held 13-18 August in Seattle, Washington. Intended to promote an understanding of fundamental shock physics, to highlight current research in the many related fields, and to discuss the application of various aspects of shock physics, the conference provides an international forum for technical exchange among scientists, engineers, academic professionals, users, and industrialists. Sonoluminescence. Sonoluminescence is a phenomenon which involves the conversion of acoustical energy to optical energy arising from the nucleation, growth, and collapse of gas-filled bubbles in a liquid. The process of generating light appears to be extremely rapid and represents a remarkable -degree of energy concentration, i.e., as high as 12 orders of magnitude. Recent experimental -advances have pro-duced a single acoustically levitated sonoluminescent air bubble with unanticipated temporal and spectral properties, which are inconsistent with existing models of sonoluminescence. According to Lawrence Crum of the Applied Physics Laboratory in Seattle, Washington, the most plausible explanation of the origin of the extremely short bursts of light emitted from the bubble is that an imploding shock wave is generated within the bubble during the final stages of collapse. "If this shock wave does indeed exist, then preliminary computations of the final temperatures and pressures that would occur in the bubble as a result of the symmetric implosion of the shock wave indicate temperatures in excess of a million degrees and pressures on the order of megabars," he said.

Extractions: Title: Effects of Thermal Conduction in Sonoluminescence Authors: M. Chu and D. Leung Abstract: We show by numerical hydrodynamic calculations that there are three important effects of thermal conduction in Sonoluminescence: 1.~the bubble remains close to being isothermal during the expansion phase; 2.~a cold, dense layer of air is frozen at the bubble wall during the contraction phase; 3.~shock waves generated at the late contraction phase are significantly weakened. For a range of water temperature, our results agree with the observed expansion ratio, as well as the scaling of the light intensity if black body radiation is assumed.

http://van.hep.uiuc.edu/van/qa/section/Light_and_Sound/Glowing/889488529.htm

Extractions: For a brief fraction of a second, the gas is compressed so much that it heats up until it glows. What we see is a little flash of light. That light flashes with each wave of sound that hits the bubble. It looks like a continuous spark of light in the middle of the water. Even though the equipment can be bought for a few hundred dollars, getting everything perfect so that it works is difficult. You need a very spherical flask, ultrasonic speakers around the outside surface of the flask and electronics to drive the speakers. Experimenters also put different gasses in the water to see what happens.
