Dr. Gennadii Liziakin
My research focuses on the dynamics of plasma systems in which macroscopic behavior emerges from the competition between transport, ionization, electromagnetic fields, and plasma–boundary interactions. I am particularly interested in identifying the physical mechanisms that determine this behavior and in using them for plasma control. My main scientific contributions include the description of plasma potential control using biasing electrodes in linear plasma devices and the investigation of high-throughput plasma mass separation in crossed E × B fields.
My research interests cover plasma physics in its various manifestations. I have extensive experience in the experimental investigation of low-pressure gas discharges, including reflex discharges, arc discharges, and inductively coupled plasmas, using various probe-based and spectroscopic diagnostic methods.
I also have significant experience in pulsed-power plasma physics, in particular in the study of high-power microwave devices, such as vircators and relativistic magnetrons, driven by high-voltage, high-current pulse-forming networks with typical parameters of 300 kV and 20 kA.
In addition, I have experience in numerical CFD modelling of thermal atmospheric-pressure plasmas for spacecraft re-entry applications using ANSYS Fluent and System Coupling with Fluent and Maxwell. I have also modelled nonlinear Joule heating in thin-foil explosions in COMSOL Multiphysics, including three-dimensional, fast foil heating on the 200–600 ns timescale, magnetic diffusion, phase-transition effects, and temperature-dependent material properties.
I would be pleased to discuss potential collaborations.
