Thermal conductivity of a laser plasma

Physical Review E, 2023
We present a model of the electron thermal conductivity of a laser-produced plasma. The model, supported by Vlasov-Fokker-Planck simulations, predicts that laser absorption reduces conductivity by forcing electrons out of a Maxwell-Boltzmann equilibrium, which results in the depletion of both low-velocity bulk electrons and high-velocity tail electrons.

ADVANCED THERMAL PLASMA MODELLING

High Temperature Material Processes (An International Quarterly of High-Technology Plasma Processes), 2008
The advanced techniques that have been applied to the computational modelling of thermal plasmas in the last ten to fifteen years are reviewed. The techniques considered include three-dimensional and time-dependent models, sophisticated treatments of plasma turbulence and radiative transfer, modelling of demixing and of deviations from thermal and ...

PLASMA THERMALIZATION

The Twelfth Marcel Grossmann Meeting, 2012
We have studied thermalization of optically thick pair plasma with baryon loading by particle collisions and followed the evolution of distribution functions starting far from equilibrium con…guration. With this goal we solved numerically relativistic Boltzmann equations with collisional integrals given by QED matrix elements for the corresponding ...

Thermal evolution of flare plasma

Solar Physics, 1983
The evolution of hot thermal plasma in solar flares is analyzed by a single-temperature model applied to continuum emission in the 5 keV < E < 13 keV spectral range. The general trend that the thermal plasma observed in soft X-rays is heated by the non-thermal electrons that emit as the hard X-ray bursts is confirmed by the observation of an electron ...

Stabilization of thermal plasma in an plasma generator

IEEE Conference Record - Abstracts. PPPS-2001 Pulsed Power Plasma Science 2001. 28th IEEE International Conference on Plasma Science and 13th IEEE International Pulsed Power Conference (Cat. No.01CH37255), 2002
Summary form only given, as follows. A simple-structured thermal plasma generator for waste treatment has been studied. The thermal plasma technology applied to waste treatment has undoubtedly gained high importance owing to its outstanding properties such as flexibility, compact reactor, and clean treatment.

Generation and Thermalization of Plasma Waves

The Physics of Fluids, 1958
Generation of hydromagnetic and ion cyclotron waves by an induction coil is considered for a cylindrical plasma in a uniform confining magnetic field. Resonance widths are calculated and power absorption is calculated and compared to ohmic losses in the induction coil.

Plasma generators for thermal plasma processes

International Journal of Materials Research, 2011
Abstract An overview is given of Plasma Generators developed with the focus on application in thermal spraying, some of which might even find use in other thermal plasma processes. The construction and operation principle of conventional plasma torches as well as of plasma torches with special features are presented.
