Sentence examples for charged grains from inspiring English sources
Although spokes were observed frequently during the Voyager encounters, they were not seen during the Cassini mission until September 2005, possibly an indication of the effect of a different Sun angle on the production of charged grains.
It is shown that, under specific conditions for the dust and plasma, oppositely charged grains may exist without the necessity of a temperature fluctuation.
The charging profiles of micron- and submicron-sized dust grains immersed in such plasma environments are strongly size- and temperature-dependent, and under certain conditions, the dust cloud can have various configurations of charged grains.
Previous models have explained micron-sized dust observed at ∼10 cm above the surface, by suggesting that charged grains "levitate" in the local electric field; however this cannot account for observations of 0.1 μm-scale grains at ∼100 km altitude.
Using a standard grain charging model along with a modified Barnes–Hut tree code for calculating grain dynamics, this paper examines the effect of including initial grain charging in coagulation of clouds of negative grains, positive grains, and a mixture of oppositely charged grains.
The authors described briefly the possibility of charged grains forming a Coulomb lattice.
The dispersion Eq. (12) carries a term ( alpha^{2} ), it means the same results are expected for the cases of positively charged dust grains and negatively charged dust grains.
They derived the KdV equation and reported that the amplitude of a compressive soliton remains larger in case of positively charged dust grains as compared to dust grains having negative charge.
Moreover, it is also noticed that the amplitude of such solitons remain larger in the case of positively charged dust grains in comparison with negatively charged dust grains.
Moreover, the amplitude of such a soliton remains larger in the case of positively charged dust grains in comparison with the negatively charged dust grains.
The soliton amplitude increases with increasing temperature ratio of free to trapped electrons for both positive and negative dust grains; but Fig. 1 indicates that amplitude goes higher for increasing the number density of positively charged dust grains whereas the amplitude decreases with increasing the negatively charged dust grain number density.
