Closure of project KIT-PLASMEBA

Project KIT-PLASMEBA was closed on 26 July 2019, with an informal lunch and meeting of the team.
The project delivered: (i) the tools LoKI-B (open-source), LoKI-(B+C), LoKI-B++ (the C++ version of LoKI-B, in progress), with new versions to be released soon; (ii) the first kinetic schemes for N2, O2, He, Ar and N2-O2 (in progress), currently under validation.
The project followup will focus on the definition of reaction schemes and the development of chemistry databases.

Argon KIT - results

The figures show example results, obtained for argon plasmas at low and moderate pressures, with the simulation tool LisbOn KInetics - LoKI: the electron energy distribution function (1); the distribution of the electron power-density (2); and the densities of charged and neutral species (3).

Helium KIT - results

The figures show example results, obtained for helium plasmas at low and moderate pressures, with the simulation tool LisbOn KInetics - LoKI: the electron energy distribution function (1); the distribution of the electron power-density (2); and the densities of charged and neutral species (3).

Oxygen KIT - results

The figures show example results, obtained for oxygen plasmas at low and moderate pressures, with the simulation tool LisbOn KInetics - LoKI: the electron energy distribution function (1); the distribution of the electron power-density (2); the densities of atomic / molecular charged and neutral species (3); and the distribution of densities for the vibrational excited states with the electronic ground-state O2(X) (4).

Nitrogen KIT - results

The figures show example results, obtained for nitrogen plasmas at low and high-pressures, with the simulation tool LisbOn KInetics - LoKI: the electron energy distribution function (1); the distribution of the electron power-density (2); the densities of atomic / molecular charged and neutral species (3); and the distribution of densities for the vibrational excited states with the electronic ground-state N2(X) (4).

LoKI-B released as open-source tool

The simulation tool LisbOn KInetics (LoKI), developed in the framework of project KIT-PLASMEBA, couples two main calculation blocks: a Boltzmann solver (LoKI-B), released as open-source code on March 23, 2019, and a Chemistry solver (LoKI-C).
LoKI-B was developed as a response to the need of having an electron Boltzmann solver easily addressing the simulation of the electron kinetics in any complex gas mixture (of atomic/molecular species), describing first and second-kind electron collisions with any target state (electronic, vibrational and rotational), characterised by any user-prescribed population.

Nitrogen KIT concluded - more to come

The simulation tool LisbOn KInetics - LoKI was successfuly used to propose a KInetic Test Scheme (KIT) for nitrogen plasmas at low and high-pressures, including a mixture of N2 / N ground-state and excited-states (electronic, vibrational and rotational).
More details to be disclosed soon.

Presentation of LoKI-B at the 2018 International School on Low Temperature Plasma Physics: Basics and Application

On October 2018, Luís L. Alves and Antonio Tejero delivered the modelling workshop "Hands on a Boltzmann solver" within the 2018 program of the International School on Low Temperature Plasma Physics: Basics and Application (Bad Honnef, Germany), using for the first time the LisbOn KInetics Boltzmann solver (LoKI-B) in a classroom environment.

Presentation of LoKI at CRC1316

On July 2018, the Ruhr Universitat Bochum (RUB, Bochum, Germany) welcomed a seminar by Luís L. Alves and Antonio Tejero presenting the state of development of the simulation tool LisbOn KInetics - LoKI (partly to become open-source), for the coupled solution of the electron Boltzmann equation and a chemistry global model. The presentation was included in the first project meeting of the CRC1316, which took place in Kerkrade.

Presentation of LoKI at YIP

On May 2018, the York Institute of Physics (YIP, York, UK) welcomed a seminar by Luís L. Alves and Antonio Tejero presenting the state of development of the simulation tool LisbOn KInetics - LoKI (partly to become open-source), for the coupled solution of the electron Boltzmann equation and a chemistry global model.

Presentation of LoKI at LPP and LPGP

On February 2018, the Laboratoire de Physique des Plasmas (LPP, Palaiseau, France) and the Laboratoire de Physique des Gaz et des Plasmas (LPGP, Orsay, France) welcomed seminars by Luís L. Alves and Antonio Tejero presenting the state of development of the simulation tool LisbOn KInetics - LoKI (partly to become open-source), for the coupled solution of the electron Boltzmann equation and a chemistry global model.

Workshop on Input Data for Plasma Modeling

KIT-PLASMEBA was at the “Workshop on Input Data for Plasma Modeling” on April 22, at TU/e.
Recently, the availability of reliable input data for plasma modeling has been attracting an increasing level of attention. At this moment, there’s no facility for curating data on plasma chemistry, on photon induced processes, or on surface processes. The LTP community is trying to organize itself in order to overcome this limitation.
