“…Some other ways are also used to produce transient cavitation bubbles named as single cavitation bubble luminescence (SCBL), such as electrical discharge [19,20], syringe injection of gas into a venture flow field [21], or colloidal particle suspensions [22]. In recent years, the applications of a focused laser beam have become a very attractive way of obtaining SCBL due to its unique features [23,24].…”

Quasiadiabatic approach for laser-induced single-bubble sonoluminescence

The luminescence parameters of laser-induced bubble in the presence of an acoustic field in water are studied. A comparison is made between parameters such as bubble radius, interior temperature, and pressure of the bubble induced by laser and an acoustic field influenced by different driving pressure amplitudes. It is found that the bubble volume induced by laser at the collapse instant is more than 10(6) times larger than the one induced by an acoustic field. It is also noticed, by increasing the driving pressure amplitude, the bubble radius decreases in both cases, however, the bubble interior pressure and temperature increase.

“…The bubble collapse results in a very high pressure, forming a shock wave which is sent towards the outside of the bubble. Harrison [10] in his experimental results proved the existence of a noise generated by the collapse of bubble at its surrounding rigid boundary. Vogel and Lauterborn [11] found a close relationship between the strength of the wave pulse and the distance between the position of the bubble and the rigid boundary.…”

“…The initial formation and increment of the size of the counter jet is very rapid and it could exist for a while. Experiments related to the counter jet is found in Harrison [10] and Kling and Hammitt's [23] researches but it is until Lauterborn [24] who first described the counter jet phenomenon. There has not been a final conclusion for the cause of the generation of the counter jet.…”

This study utilized a U-shape platform device to generate a single cavitation bubble for the detail analysis of the flow field characteristics and the cause of the counter jet during the process of bubble collapse induced by pressure wave. A series of bubble collapse flows induced by pressure waves of different strengths are investigated by positioning the cavitation bubble at different stand-off distances to the solid boundary. It is found that the Kelvin-Helmholtz vortices are formed when the liquid jet induced by the pressure wave penetrates the bubble surface. If the bubble center to the solid boundary is within one to three times the bubble's radius, a stagnation ring will form on the boundary when impacted by the penetrated jet. The liquid inside the stagnation ring is squeezed toward the center of the ring to form a counter jet after the bubble collapses. At the critical position, where the bubble center from the solid boundary is about three times the bubble's radius, the bubble collapse flows will vary. Depending on the strengths of the pressure waves applied, either just the Kelvin-Helmholtz vortices form around the penetrated jet or the penetrated jet impacts the boundary directly to generate the stagnation ring and the counter jet flow. This phenomenon used the particle image velocimetry method can be clearly revealed the flow field variation of the counter jet. If the bubble surface is in contact with the solid boundary, the liquid jet can only splash radially without producing the stagnation ring and the counter jet. The complex phenomenon of cavitation bubble collapse flows are clearly manifested in this study.

“…4,7 Another way to produce similar phenomena ͑pressure waves and bubble formation͒ is to use spark discharge in liquid. [8][9][10] However, in this case, bubble formation takes place after a series of very complex events occurring into a propagating canal discharge created between the electrodes ͑electron avalanches, phase change, streamer, and leader formation, etc.͒ leading to the total collapse of the voltage, a large energy injection ͑mJ to kJ͒ and, therefore, a large bubble size ͑mm to m͒. Moreover, here the injected energy is deposited in some s in medium of evoluting characteristics in time from the liquid phase to a gaseous canal at low temperature ͑streamer͒ and then to a canal at high temperature ͑arc͒.…”

The experimental results reported in this paper mainly concern the two first transient pressure waves emitted after a fast (approximately ns) and localized (approximately micron) injection of electrical energy Wi in insulating liquids. The influence of various parameters (hydrostatic pressure P infinity, injected energy Wi, etc.) on the relative amplitude of these two transient pressure waves are presented and discussed. The analysis shows clearly a difference of behavior, in particular their dependence as a function of hydrostatic pressure, between these two waves. Basically, the physical processes leading to their emission are quite different. The first pressure transient is a consequence of the plasma relaxation, whereas the second one is due to the bubble collapse. According to these results, the chronology of the events is more improved, as well as the theoretical analysis.
