Comparisons of computational methods to represent electron transport in nonequilibrium plasma devices
Low pressure optically triggered pseudosparks, or Back-Lit Thyratrons (BLT), are inherently multidimensional transient devices. The method employed to model electron transport in such devices is therefore problematic. A versatile model for these switches with which to compare different modeling …

Hybrid plasma-semiconductor devices
A hybrid plasma-semiconductor phototransistor has been realized by substituting a plasma for the collector of an npn bipolar junction transistor. Designated as the plasma bipolar junction transistor (PBJT), this optoelectronic device relies on the correspondence between the properties of a low …

Ignition and hydrodynamic ejections by laser-induced breakdowns
… breakdown of gas, forming a high-temperature plasma that rapidly absorbs laser energy. As a source of heat and radical species, laser-based energy deposition can be an effective ignition source, and its relative versatility and precision make it an attractive alternative to conventional …

Multi-scale modeling of nanosecond plasma assisted combustion
… However, a comprehensive understanding of nonequilibrium plasma effects (in situ generation of reactive species and radicals combined with gas heating) on the combustion process is still lacking. Over the past decade, research efforts have advanced our knowledge of electron impact kinetics …

Physics-informed neural surrogates for next-generation aerothermochemical modeling
Thermochemical nonequilibrium is a fundamental physical process in a wide range of reactive flow environments, spanning planetary entry and astrophysical flows to plasma-assisted combustion and flow control. State-to-state (StS) collisional–radiative (CR) models provide the highest level of …
