Excitation Temperatures in the Hollow Cathode Discharge
Applied Spectroscopy, 1981Excitation or spectroscopic temperatures have been determined for various operating conditions of a hollow cathode discharge. It was found that the temperatures measured do not significantly change over the range of conditions studied. These results are compared to those obtained in other low-pressure discharges.

Spectroscopic temperature measurements in a microwave discharge
Journal of Physics D: Applied Physics, 1996We report temperature measurements in a low-pressure hydrogen microwave plasma. Translational temperatures both of H and of (using Doppler broadening), as well as the rotational temperature of , are simultaneously determined. It is first shown that the rotational temperature of the excited state is not in equilibrium with the translational ...

TEMPERATURE DISTRIBUTION DURING ELECTRO-DISCHARGE ABRASIVE GRINDING
Machining Science and Technology, 2002The objective of this work is to develop a finite element method (FEM) based mathematical model to simulate the hybrid machining process of grinding and electric discharge machining (EDM), named as Electro-discharge abrasive grinding (EDAG), for temperature distribution in the workpiece.

Low-temperature electrical discharge through solid xenon
Low Temperature Physics, 2008A uniform self-sustained electrical discharge through solid xenon is realized and studied. The multiplication of electrons proceeds in the noble gas above the xenon crystal interface, whereas a positive feedback is realized on account of multiple exciton formation by excess electrons drifting through the crystal: molecular excitons emit VUV photons ...

Two-Temperature Simulation of Subatmospheric Arc Discharge
2019 IEEE Pulsed Power & Plasma Science (PPPS), 2019A two temperature model was used to simulate the arc discharge process used for synthesizing nanoparticles. A 60 A arc between graphite electrodes placed inside a sub atmospheric chamber was simulated. Helium was used as the background gas and the chamber pressure was 10 Torr.

Neuro-models for discharge air temperature system
Energy Conversion and Management, 2004Nonlinear neuro-models for a discharge air temperature (DAT) system are developed. Experimental data gathered in a heating ventilating and air conditioning (HVAC) test facility is used to develop multi-input multi-output (MIMO) and single-input single-output (SISO) neruo-models. Several different network architectures were explored to build the models.

Vibrational temperatures of pulse-excited torch discharge
Czechoslovak Journal of Physics, 1965At the beginning of the exciting period in a pulse-excited torch discharge only a high-frequency corona is formed and this slowly changes a torch discharge. The vibrational temperatures determined from two different sequences of vibration bands of the 2-positive group N2 differ from one another up to the time when the torch discharge forms its own ...
