Overview on Studies of Martian Like Co2-N2 Mixture by Inductively Coupled Plasma Torch

TL;DR

This paper reviews studies on Martian-like CO2-N2 plasmas generated by inductively coupled plasma torches, focusing on their radiative properties and potential for validating radiation models under various conditions.

Contribution

It provides an overview of plasma properties and experimental conditions for Martian-like CO2-N2 mixtures created by ICP torches, aiding future research and model validation.

Findings

ICP torches produce stable, non-electrode plasmas with variable thermodynamic states.

Radiative properties of Martian-like plasmas are characterized for model validation.

The study sets the groundwork for further detailed analysis in subsequent papers.

Abstract

The purpose of the work is to make an overview on the results obtained through the studies on martian plasmas created by inductively coupled plasma torches (ICP). As the main advantage of the ICP torch is the absence of electrode compared to the others various test facilities, the radiative properties of this kind of plasmas are of interest to propose test cases in order to validate radiation models. ICP torches can work under various operating conditions in terms of pressure, enthalpy or flow. As a consequence, the studied plasma can be either at thermodynamical equilibrium or out of equilibrium, without problems of stability in time. The presentation concerns only the plasmas formed with a martian like CO2-N2 mixture and all the parameters of test facilities will be precised. The following paper corresponds to the first step of a global paper which will be proposed later and it reports only the oral presentation which has been done during the third International Workshop of RHTG.
