讲座提纲

4. Simple hybrid approach for simulations of DC glow discharges.

In this lecture I will present:

- the basic idea and formulation of simple hybrid approach for simulations of DC glow discharges

- demonstration of reproducibility of main discharge properties in simulations using the approach

- analysis of electron energy balance equation as formulated within the approach

- comparison with experiment, discussion of results

- formulation of models of DC discharges with gridded electrodes based on the simple hybrid approach and simulation results

- prospects for future work on the topic

5. Analytical methods for description and analysis of DC glow discharges.

In this lecture I will talk about:

- introduction about place of analytical models in moder ngas discharge physics

- formulation of an analytical model of a short (without positive column) DC glow discharge with step-by-step derivation of formulas for plasma density and current voltage characteristics

- same as previous, but with included account of charged particle losses on discharge walls

- demonstration of calculations using derived formulas and comparison with COMSOL experiment

- prospects of future work on the topic

6. Fluid simulations of thermionic devices and arc-discharge-based devices using COMSOL Multiphysics.

This one will include:

- overview of previous work on the topic (hollow cathodes for SPT-100 and MHD thrusters, what was done right and was done wrong)

- introduction into fluid simulations of discharges with thermionic emission

- overview of work on development of self-ignition technology

- concluding remarks
