Plasma Modelling

Modelling of plasma sources and plasma reactors plays a central role in the field of plasma research and plasma technology. Based on extensive parameter studies, model calculations and simulations enable the specific optimization of technological plasmas as well as the development of new applications. The performance of cost-intensive and time-consuming experiments can be reduced by means of modelling. In addition, model calculations and simulations allow the determination of parameters, which cannot or are difficult to be measured, and thus make the analysis of their behaviour possible.

At INP Greifswald models and simulations are predominantly developed and applied for the technological and scientific utilization potential of non-thermal plasmas at low and at­mo­s­phe­ric pres­su­re. The spectrum of models extends from the description of individual plasma effects to the complete modelling of plasma sources and plasma processes. In this regard, the focus is currently on plasma sources for surface modification and for energy and environmental applications, on plasma processes for the de­gra­da­ti­on or conversion of pollutants, as well as on arc plasmas for welding, cutting and switching. Furthermore, solutions for the management of research data are worked out that should enable an improved subsequent use of the interdisciplinary results of the plasma technology.
