Composition, thermodynamic properties and transport coefficients

Composition, thermodynamic properties and transport coefficients (viscosity, thermal and electrical conductivity, diffusion) are requite to make models (fluid dynamic) and can help to the interpretation of experimental results.

Two main kinds of plasmas can be classified in our laboratory: plasma at thermal equilibrium and plasma out of thermal equilibrium

Plasma at thermal equilibrium

Scientific team : André P., Mahfouf A.

At the present time, we can calculated the composition, the thermodynamic properties, and the transport coefficients of plasmas formed with Ag, Al, Ar, C, Cl, Cu, F, H, Mg, N, Ni, O, S, Si. The calculation can be made at a fixed volume or at a fixed pressure that allow us to use them in industrial applications: HBC fuses and electrothermal-chemical gun (ETC).

Electrical conductivity for three pressures and two insulators.

Viscosity for three pressures and two insulators.

Thermal conductivity for three pressures and two insulators.

Plasma out of thermal equilibrium

Scientific team : André P., Aubreton J*., Elchinger M.F.*, Fauchais P.*, Lefort A., Rat V.*
* SPCTS, Université de Limoges, 123 rue Albert Thomas, 87060 Limoges, France

Working together with SPCTS laboratory of Limoges University, we have developed a new theory based on Chapman-Enskog method to calculate transport coefficients in plasma out of thermal equilibrium. The calculation of transport coefficient depends on the composition that has to be determine versus physical constraints.
