The PlasMa Project will contribute to the development and recognition of research in plasma science and technology with energy applications at an international level and therefore will make the Region recognized for research carried out in this area, through the publication of scientific articles in the most important international journals of the area and for the collaboration, already underway, in RTD + I projects with international partners of excellence.
The project is dedicated to the research of two types of gas discharges in high-pressure gases, which constitute R&D sub-projects:


Sub-project Arc: plasma-electrode interaction in high pressure arc discharges, including electrode erosion

Objective
  • Develop a fast, robust and accurate tool for modeling high pressure arc discharges considering the plasma-electrode interaction in a self-consistent way.
Specific actions to be taken
  • Refinement of boundary conditions that describe the energy exchange between the cathode and the volume of the arc without introducing a more complex structure of the arc close to the cathode region;
  • Ensure a complete coupling (thermal and electrical) of the cathode with the plasma by taking into account the variation, along the cathode surface, of the voltage drop in the plasma layer next to the cathode, due to the electrical resistance of the arc volume;
  • Coupling the models of arc discharges and surface discharges and streamers with the code that simulates the processes inside the cathode, including the vaporization of the cathode material and the eventual formation of craters and the ejection of drops;
  • Development of an integrated code, which will work for any set of parameters of interest, and which will allow a transition between the models of arc discharges and streamer discharges as appropriate. This code will be ready to be used for industrial applications.
Expected results
  • Integrated code, which will work for any set of parameters of interest, and which will allow a transition between the models of arc discharges and streamer discharges as appropriate. This code will be ready to be used for industrial applications;
  • Publication of 10 scientific articles in the best international journals in the relevant areas.

Sub-project Streamers: disruption and surface streamers in high pressure gases.

Objective
  • Develop a code capable of predicting gas disruption conditions in a wide range of conditions, including the effects of the presence of dielectrics and time-varying fields. This code will be ready to be used for energy applications.
Specific actions to be taken
  • Development of a code capable of predicting gas disruption conditions in a wide range of conditions, including the effects of the presence of dielectrics and time-varying fields;
  • Validation of the code with other numerical results and also experimental results.
Expected results
  • Code capable of predicting gas disruption conditions over a wide range of conditions, including the effects of the presence of dielectrics and time-varying fields. This code will be ready to be used for energy applications;
  • Publication of 5 scientific articles in the best international journals in the relevant areas.

The sub-projects will be developed in collaboration with leading international partners in their respective areas.
