Thermochemical Non-Equilibrium in Thermal Plasmas

Thermo - chemical dynamics and chemical quasi - equilibrium of plasmas in thermal non - equilibrium

Plasmas have a broad field of applications, such as air-breathing hypersonic vehicles (plasma control for scramjet engine), spacecraft atmospheric entries (influence of precursor electrons and prediction of blackout phenomenon), high-enthalpy wind tunnels (plasmatron, arc-jet, and shock tube facilities), lightning phenomena, discharges at atmospheric pressure, laboratory nuclear fusion and astr...

Complex non-equilibrium dynamics in plasmas

In this contribution we will discuss two new forms of strongly coupled plasmas which have become possible to create and observe in the laboratory only recently. They exhibit a wealth of intriguing complex behavior which can be studied, in many cases for the first time, experimentally. Plasmas, gases of charged particles, are universal in the sense that certain properties of complex behavior do ...

Modulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons

  Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...

Inactivation of Bacteria by Non-Thermal Plasmas

The Physics of Hybrid Thermal/Non-Thermal Plasmas

Models of the continuum radiation from accreting hot plasmas typically assume that the plasma heating mechanism produces energetic particles distributed in energy either as a Maxwellian (the “thermal” models) or as an extended power law (the “non-thermal” models). The reality, however, is that neither description is probably accurate. In other astrophysical contexts where we have been able to o...
