Effect of Electromagnetic Boundary Conditions on Reliability of Plasma Torch Models
Journal of thermal spray technology (Print), 2020 The cascaded-anode plasma torch makes it possible to get a longer and more stable plasma jet with higher specific enthalpy than conventional plasma torches. It is now used widely, but there are still few models of the cascaded-anode plasma torch.

Chemical mechanisms inducing a dc current measured in the flowing post-discharge of an RF He-O2 plasma torch [PDF]
Plasma Sources Science and Technology, IOP Publishing, 2012, 21,
045013 (10pp), 2016 The post-discharge of an RF plasma torch supplied with helium and oxygen gases is characterized by mass spectrometry, optical emission spectroscopy and electrical measurements. We have proved the existence of a dc current in the post-discharge (1--20 A), attributed to the Penning ionization of atmospheric nitrogen and oxygenated species. The mechanisms

Multi-domain analysis and prediction of the light emitted by an inductively coupled plasma jet [PDF]
, 2023 Inductively coupled plasma wind tunnels are crucial for replicating hypersonic flight conditions in ground testing. Achieving the desired conditions (e.g., stagnation-point heat fluxes and enthalpies during atmospheric reentry) requires a careful selection of operating inputs, such as mass flow, gas composition, nozzle geometry, torch power, chamber ...
