Dust-Acoustic Waves: Visible Sound Waves
A historical overview of some of the early theoretical and experimental work on dust acoustic waves is given. The basic physics of the dust acoustic wave and some of the theoretical refinements that have been made, including the effects of collisions, plasma absorption, dust charge fluctuations, particle drifts and strong coupling effects are discussed. Some recent experimental findings and out...
متن کاملModulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons
Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...
متن کاملDust-acoustic waves driven by an ion-dust streaming instability in laboratory discharge plasma experiments
Dust acoustic waves (DAW) are spontaneously excited in dusty plasmas produced in dc and rf discharge plasmas over a wide range of plasma and dust conditions. A common feature of these plasmas is the presence of an ion drift relative to the dust, which is driven by an electric field, Eo in the discharge. Using a three fluid model of the DAWs, including the zero order electric field and collision...
متن کاملDust Acoustic Waves
In dc glow discharge dusty plasmas, the formation of dust acoustic waves is a commonly observed phenomenon. Experiments in the dusty plasma experiment device produce naturally occurring dust acoustic waves with frequencies f N 5 to 25 Hz and phase velocities of Vph N 0.5 to 10 cm/s. Through the use of particle image velocimetry techniques, particle motion in the vicinity of the wavefronts is id...
