Plasmas for aerospace

Numerical codes implementing kinetic, PIC, DSMC and fluid dynamic approaches and including advanced state-to-state chemical-physical models are used for the investigation of plasmas of interest for aerospace applications, with particular attention to the simulation of non-equilibrium conditions in planetary entry conditions, dusty plasmas and plasma propulsion systems.

Hypersonic Flows

The reliable prediction of thermal loads on a spacecraft thermal protection systems during an high-speed entry in the atmosphere of Earth and other planets requires proper consideration of the non-equilibrium character of the flow, taking into account the elementary processes of atomic and molecular excitation, dissociation and ionization induced by collisions with heavy particles and electrons, in the state-to-state approach, extended also to more complex molecules as CO2. Radiation emitted by excited species gives a further contribution to the vehicle heat load, determined by photon transport equation.
Different non-equilibrium phenomena can be observed in the first part of the atmosphere, in very rarefied conditions, where the mean free path of particles is very long, comparable with the vehicle dimensions, needing particle simulations (DSMC). Other problems are related to the control and stability of hypersonic intercontinental flights based on SCRAMJET engine. Surface dielectric barrier discharge (DBD) is a promising technique to avoid the use of mechanical actuators, not adequate for hypersonic flights. Particle and fluid simulations have been done for modelling DBD’s. Different approaches have been used to investigate geometries, ranging from homogeneous systems to 3D flows coupling self-consistently Boltzmann and Master Equations, Radiative Transfer Equation (RTE), Boundary Layer or Navier-Stokes Equations.

Space Plasmas

Plasma is the most diffuse matter state in the Universe, where conditions are often very extreme, from very low to very high density. This research line starting from fundamental aspects has different applications.

» Dusty Plasmas
The interaction of space dust in the surrounding plasma determines charging/growing dynamics and transport of dust grains. This research line deals with the dynamics of dust above airless body surfaces, rings and planetesimal formation.

» Nanoconfined Atoms and Molecules
Atomic species in high-density plasma, as met in star, are investigated by means of quantum theory. Modification of the atomic structure has relevant effects in thermodynamics and transport properties.

» Astrochemistry
The study concerns the chemical kinetics of the formation of the first molecules and the effect of the distribution of energy on the reaction mechanisms in space environment.

» Scientific space mission design
The advances in theoretical and numerical study of plasma turbulence require constant validation from in-situ observations. This calls for the progressive improvement and specific design of scientific space mission, that need to provide the observables necessary for the validation of the theory. NANOTEC_Rende actively participates in the design and realization of ESA and NASA space missions, such as ESA/THOR, ESA/Solar Orbiter and NASA/GRIPS.

Plasma for Space Propulsion

Electric thrusters (Hall-effect and helicon discharges) and plasma-assisted combustion (SCRAMJET) are important for space transportation (satellite guidance, orbit transfer and deep space exploration). Different numerical approaches (particle-based models and chemical kinetics) have been used to investigate non-equilibrium conditions typical of plasma propulsion systems.

EIT RawMaterials Roadshow

21 giugno 2019 ore 09:00 – 15:00

   

Lecce, Aula Fermi Edificio Aldo Romano, Campus Ekotecne, Via Lecce-Monteroni

   

Farà tappa a Lecce il prossimo 21 giugno, presso l’Aula Fermi dell’edificio IBIL all’interno del Campus Ecotekne, l’EIT RawMaterials, la piattaforma per il sostegno all’innovazione finanziata dall’Istituto Europeo di Innovazione e Tecnologia (EIT).

   

L’EIT ha creato le cosiddette KIC – Knowledge Innovation Community, comunità che mirano alla promozione dell’innovazione e della formazione in Europa in settori cruciali, sostenendo l’imprenditorialità e favorendo il passaggio di nuove idee dalla fase di incubazione al mercato.

 

La EIT RawMaterials si impegna ad affrontare la sfida globale dell’approvvigionamento delle materie prime in Europa attraverso programmi e progetti che mirano allo sviluppo di tecnologia nell’intera catena di valore delle materie prime: dall’esplorazione delle risorse, all’industria mineraria, dai processi metallurgici alla sostituzione delle materie prime critiche o tossiche, dal riciclo dei materiali dei prodotti a fine vita sino alla progettazione di prodotti per l’economia circolare. Nell’ambito dei programmi di sviluppo a livello regionale, la EIT RawMaterials ha creato un Hub nella Regione Puglia coordinato da ENEA, al fine di incrementare il coinvolgimento degli ecosistemi locali nelle attività della KIC e del suo partenariato.

 

Il MedinHub avrà inoltre l’obiettivo di raggiungere nuove organizzazioni e promuovere la partecipazione delle industrie e delle PMI più innovative, nonché il coinvolgimento delle prestigiose università e centri di ricerca dell’area.
