Theory and Simulation Laboratory (TSL) of CPP-IPR conducts research in both basic plasma physics areas and applied concepts of plasma physics.
The main areas of work of the laboratory includes
MHD Simulation: The goal of the MHD analysis of Test Blanket Modules is to estimate the MHD pressure drop and velocity distribution over the Pb-17Li flow path when the TBM operates in a performance regime. The high-performance regime depends on the required mass flow rate of Pb-Li for a maximum heat deposition in the ceramic breeders of the TBM and its efficient extraction flow parameters. We study the parameters affecting the heat transfer characteristics within the TBM under different flow conditions.
Kinetic Simulation: Collisionless simulation of nonlinear plasma dynamics is one of the outstanding problems of plasma physics as well as a strong challenge in computational physics. The physics of collisionless plasma is well described by a self-consistent of a system of Vlasov and Maxwell equation. Due to its non-locality and non-linearity in many important situations, no analytical solutions of the Vlasov equation can be found. Hence numerical solution and numerical simulation approaches are necessary. The present Vlasov code is based on time splitting and flux balance method. Using our code we study the direct evolution of distribution function such that we can have the self-consistent electric field by solving Poisson’s equation and particle flux from the first moment of distribution function at any time during evolution.
PIC Simulation: Recently some endeavor has been put on to study various physical processes requiring PIC simulation in plasma. Research on the extraction of the negative ion source is one of them. The code under development will include Monte-Carlo-collisions to take into account various collision processes within the computational region.
Complex Plasma: Beside the presence of experimental facility available in CPP-IPR to do research on complex plasmas, the theory and simulation group also take deep effort to study theoretically and numerically various complex plasma processes.
Fluid Simulation: Hall thrusters constitute an important electric propulsion technology for certain applications requiring low thrust levels, e.g. satellite station keeping and orbit transfer. The thrust in Hall thrusters is generated by ions being accelerated through annular plasma by the electric field set up between an anode and a cathode. This electric field is strongly coupled to an externally applied radial magnetic field which typically localizes the electric field near the channel exit. In our proposed work we are planning to develop a 2D steady-state and transient fluid model of stationary Hall thrusters.
Fusion Neutronics Modeling: The laboratory also conducts computer simulation in the area of fusion neutronics.
