Dynamics of laser-induced plasma splitting

Influence of ambient pressure on spatial–temporal evolution of local thermodynamic equilibrium for laser-induced plasma

“…The influence of ambient pressure on laser-induced plasma has been studied extensively. 15–19 Researchers found that ambient pressure can significantly affect the plasma morphology, 15,16 spectra, 18,19 electron temperature, electron density, 20 etc. , but there are few studies on the influence of ambient pressure on the LTE of LIP.…”

“…The inuence of ambient pressure on laser-induced plasma has been studied extensively. [15][16][17][18][19] Researchers found that ambient pressure can signicantly affect the plasma morphology, 15,16 spectra, 18,19 electron temperature, electron density, 20 etc., but there are few studies on the inuence of ambient pressure on the LTE of LIP. When the LIP is in LTE, the Boltzmann plot, the Saha-Boltzmann equation and other relatively typical methods can be used to diagnose the LIP, 9,10 which is helpful for understanding the inuence of ambient pressure on the LIP.…”

Theab initiopotential energy curves of atom pairs and transport properties of high-temperature vapors of Cu and Si and their mixtures with He, Ar, and Xe gases

“…The actual dependence of viscosity on temperature is not described by the power law in eqn (38) , thermal conductivity k (c), and thermal diffusion factor a T (d) of the Si-He (solid curves), Si-Ar (dashed curves), and Si-Xe (dashed-dotted curves) mixtures versus molar fraction of noble gas x g at a temperature of T = 300 K (red curves), 1000 K (green curves), and 5000 K (blue curves). The diffusivity is calculated at a pressure of 1 atm.…”

Study on spark discharge enhanced laser-induced breakdown spectroscopy of Fe particles in transformer oil

“…Recently, LIBS has shown excellent prospects in the power industry, such as in the pressure monitoring of vacuum interrupters 11–13 and the insulation performance evaluation of silicon rubber insulators. 14,15 The study on Fe 2 O 3 particles conducted by Stehrer et al confirmed the feasibility of LIBS in the detection of particulate matter.…”
