Ion temperature effects on plasma flow in the magnetic mirror configuration

نویسندگان

چکیده

Effects of finite ion temperature on the plasma flow in converging–diverging magnetic field, mirror, or equivalently, nozzle configuration are studied using a quasineutral paraxial two-fluid MHD model with isothermal electrons and warm magnetized ions. The acceleration was an emphasis role singularity at sonic point transition. It is shown that regularity defines global solution describing from subsonic to supersonic velocity. Stationary accelerating solutions were obtained compared time dependent dynamics, confirming time-dependent equations converge stationary and, therefore, stable. effects pressure anisotropy analyzed Chew–Golberger–Low its generalization. mirror force (manifested by perpendicular pressure) enhances acceleration. ionization charge exchange have been investigated.

Effect of Magnetic Field on the Rotating Flow in a Similar Czochralski Configuration

We present a numerical study of the rotating flow generated by two rotating disks in co-/counter-rotating, inside a fixed cylindrical enclosure similar to the Czochralski configuration (Cz).  The enclosure having an aspect ratio A = H/Rc equal to 2, filled with a low Prandtl number fluid (Pr = 0.011), which is submitted to a vertical temperature gradient. The finite volume method has been used ...

Effects of Ion Temperature on Collisional DC Sheath in Plasma Ion Implantation

The collision frequency should definitely be taken into account in high pressure discharges. In this work by using forth order of Rung Kuta method, and two-fluid model, temperature dependence of the characteristics of a collisional DC plasma sheath, such as electric field, electric potential, ion and electron number density, and ion velocity, has been studied. It will be shown in the constant c...
