Submitted for the DPP10 Meeting of The American Physical Society A Simple Method to Measure the Interaction Potential between Dielectric Grains in a Dusty Plasma ZHUANHAO ZHANG, KE QIAO, JIE KONG, LORIN MATTHEWS, TRUELL HYDE, CASPER Baylor University — A simple, minimally perturbative method is introduced to experimentally measure the interaction potential between two individual dust particles,...

Dust acoustic solitary waves are studied in warm dusty plasma containing negatively charged dusts, nonthermal ions and Boltzmann distributed electrons. Sagdeev pseudopotential method is used in order to investigate solitary wave solutions in the plasmas. The existence of compressive and rarefractive solitons is studied. Keywords—Nonthermal, Soliton, Dust, Sagdeev potential

A vibrational model of heat conduction in liquids with soft pairwise interactions is applied to estimate the thermal conductivity coefficient strongly coupled Yukawa fluids. reasonable agreement available data from numerical simulations observed. The results can be useful context plasma and complex (dusty) fluids, when (or screened Coulomb) interaction potential applicable.

background: the present study investigated the effect of the middle east dust storm episodes on the concentration and composition of pm 10 during april to september 2013 in sanandaj city, western iran. methods: sampling was once every six days, and on dusty days using an omni air sampler. the pm 10 sample was collected on polytetrafluoroethylene filters. average of 24 h values of pm 10 mass con...

The mobility of a charged projectile in a strongly coupled dusty plasma is simulated. A net force F, opposed by a combination of collisional scattering and gas friction, causes projectiles to drift at a mobility-limited velocity up. The mobility μp=up/F of the projectile's motion is obtained. Two regimes depending on F are identified. In the high-force regime, μp∝F0.23, and the scattering cross...

Dust acoustic waves are very low frequency modes associated with the dynamics of charged dust in a plasma. These waves have phase speed much smaller than the ion thermal speed and frequencies typically below the dust plasma frequency which can be on the order of hertz to hundreds of hertz for typical lab dusty plasma parameters. When the phase speed of the wave is much larger than the thermal s...
