The radiative heat transfer in arc plasma models is considered from the point of view of its description in terms of a net emission coefficient, the method of spherical harmonics in its lowest order, and the discrete ordinate method. Net emission coe

A two-dimensional and stationary magnetohydrodynamic model of a plasma spray torch operated with argon is developed to predict the plasma properties in a steady operating mode. The model couples a submodel of a refractory cathode and its non-equilibr

A previously developed unified model of a tungsten-inert gas (TIG) microarc has been extended to take into account the melting of the anode made of copper and the release of copper atoms due to its evaporation. The copper atoms enter the plasma to be

A plasma source based on a microwave discharge at atmospheric pressure is used to produce an oxygen plasma torch. An admixture of liquid precursor material is evaporated and injected into the torch through a nozzle, causing oxidization and deposition

In this paper, we present results obtained by a non-equilibrium modelling and experiments on low-intensity short-length arcs in argon at atmospheric pressure. Two modelling approaches are applied. The first one implies a non-equilibrium description o

Analysis of the plasma parameters of a tungsten-inert gas microarc with a length of 0.4 mm is carried out by means of a unified one-dimensional model. The model solves the fluid equations for the particle and energy conservation of the electrons and

The paper gives an overview of the influence of the description of the electron transport properties on the characteristics of a DC microplasma in argon at atmospheric pressure. A spatially one-dimensional model is presented which solves the equation

This work presents results of a self-consistent modelling analysis on microwave plasma generated in Ar–O2 mixtures at a frequency of 2.45 GHz at atmospheric pressure. The study focuses on how the plasma properties are influenced by the increase of
