H. Akbarian Shourkaei
Abstract
The characteristics of dust in a plasma sheath are investigated in the presence of an external magnetic field and taking into account neutral collision forces. By using the fluid model, the continuity and momentum equations of ions and dusts are solved numerically with various magnitudes of collision force. In various magnitude and directions of the magnetic field, the electron and ion density distribution, ion flow velocity, electron potential have been calculated. It is shown that magnetic field has obvious effect on the plasma sheath and the collision force reduces the dust kinetic energy.
Kurzfassung
Die Eigenschaften des Staubes in einer Plasmahülle bei Vorhandensein eines externen Magnetfeldes wurden untersucht unter Berücksichtigung neutraler Kollisionskräfte. Die Kontinuitäts- und Impulsgleichungen von Ionen und Staub werden mit Hilfe des Flüssigkeitsmodells numerisch gelöst bei verschieden starken Kollisionskräften. Die Elektronen- und Ionendichteverteilungen, die Geschwindigkeit des Ionenflusses und das Elektronenpotential wurden bei verschiedener Stärke und Richtung des Magnetfeldes berechnet. Dabei wird gezeigt, dass das Magnetfeld deutliche Auswirkungen auf die Plasmahülle hat und die Kollisionskräfte die kinetische Energie des Staubes reduzieren.
