Numerical simulation of an argon swirling flow in the presence of a DC discharge

Plasma vortex reactor for production of heat energy and hydrogen

“…A qualitative agreement between the results of the calculations and the experimental data for pure argon [8] has been obtained. The next step in the simulation of the PVR is the calculation for real mixtures of Ni, H2O, Ar, taking into account the plasma-chemical kinetics of the discharge mixture components as well as thermal characteristics of the experimental set up.…”

“…It is shown that the recirculation zone forms in such system and its characteristics strongly depend on the heat source power and the shape of electrodes and their location. A qualitative agreement between the results of the calculations and the experimental data [8] has been obtained. The numerical modelling has demonstrated that it is possible to configure electrodes in such a way as to ensure energy transfer mainly downstream from the interelectrode zone.…”

“…Subsequently, we will solve the problem close to the experimental conditions [8], with ultimate goal of finding optimal configuration and location of electrodes.…”

“…In our simulation, the Spalart-Allmaras model was used. A detailed analysis of the use of the turbulence models in similar problems is given in [8].…”

“…It may be accomplished by the combination of thin anode and pipe-like cathode through which areas of different pressures are connected. Here, a simulation gasdynamic and thermal fields structure formed in a 3D unsteady viscous turbulent vortex flow of argon in the experimental setup [8] is carried out.…”
