Overview Experimental Diagnostics for Rarefied Flows - Selected Topics

Abstract

This article gives an overview about experimental diagnostic techniques for the investigation of rarefied flows with a special focus on techniques applicable to high-enthalpy flows occurring e.g. in electrical thrusters or plasma wind tunnels. Classical intrusive techniques like Pitot, heat flux, and enthalpy probe as well as mass spectrometry are introduced as well as non-intrusive methods like emission and absorption spectroscopy and laser-induced fluorescence (LIF) measurements. Here, main emphasis is laid on the methods applied at the IRS in order to illustrate the methods by sample results.
