Transport coefficients for Planetary Atmospheres

Transport coefficients (thermal conductivity λ, viscosity η and electrical conductivity σe) for plasmas generated in the impact of space vehicles on different planetary atmospheres (Earth, Jupiter, Mars), have been derived, in the framework of the Chapman Enskog theory, considering a high-order approximation and including also minor species. The core of the calculation is represented by the characterization of binary interactions, i.e. the derivation of collision integrals, describing the microscopic dynamics. The phenomenological approach has been proposed and validated for a number of different systems, that is based on modeling the average interparticle interaction with a phenomenological potential, whose parameters can be estimated through correlation formulas from physical properties of the collisional partners. Moreover a novel efficient algorithm has been implemented based on fractal integration.

Technology transfer

The joint research activity with Antonio D’Angola (Università della Basilicata) has led to the construction of a web-access computational tool EquilTheta, that calculates chemical equilibrium product concentrations, thermodynamic and transport properties for a given mixture in wide temperature and pressure ranges, and is the focus of a business plan for the creation of a CNR-UniBAS spin-off.

Colloidal nanocrystals (NCs) are very promising materials for photovoltaic applications since they can absorb most of the sunlight radiation, they can be synthesized in the solution phase and may coated on flexible substrates, retaining the broadband absorption and superior transport properties of traditional photovoltaic semiconductors.
