Study the Characteristic of the Coupling Parameter ( ? ) in Dusty Plasma by Computer modeling
"Coulomb coupling parameter
dust grain
dust charge
structure parameter
phase transition
screening length
radius grain
potential energy ."
Computer modeling has been used to investing the Coulomb coupling parameter ?. The effects of the structure parameter K, grain charge Z, plasma density N, temperature dust grain Td, on the Coulomb coupling parameter had been studied. It was seen that the ? was increasing with increasing Z and N, and decrease with increasing K and T. Also the critical value of ? that the phase transfer of the plasma state from liquid to solid was studied.
