Simulation Based Design of Plasma Thrusters
Electric propulsion technology, called Hall effect or stationary plasma thrusters, offers a significant weight reduction compared with traditional chemical propulsion systems. In Plasma Thrusters that special type of Electric thrusters, a stream of electrons bombards, generating a plasma that is accelerated to produce very high specific impulse for applications in the vacuum of space where less absolute power is needed.
The operation of ion thrusters in space constitutes a very interesting active plasma experiment, and the associated plasma physical dynamics are only poorly understood. We can give a detailed insight and investigation of the thruster-induced plasma environment and describe related phenomena with numerical simulation with which we attempt to explore the main dynamical phenomena in this environment.

Simulation of Complex Systems to Gain Most Optimized Configuration with Advanced Technology
Magnetized plasma simulations of realistic devices using the kinetic or the multi-fluid plasma models are examples that benefit from high-order accuracy. The multi-fluid plasma model only assumes local thermodynamic equilibrium within each fluid, e.g. ion and electron fluids for the two-fluid plasma model.
Plasma Dynamics use advanced electromagnetic FEA, CFD and particle-in-cell (PIC) codes, designed for executing multi-scale, plasma physics simulations. Based on the problem and its detail, we use special commercial code or even develop new codes and subroutines to capture the interaction between charged particles (electrons and ions) and external and self-generated electric and magnetic fields.
