The paper reports the determination of luminous efficiency values from ground testing of a
comprehensive set of meteorite samples. The ground testing data is translated with …

A combined approach for the simulation of reactive, neutral, partially or fully ionized plasma
flows is presented. This is realized in a code framework named “PICLas” for the approximate …

An Argon plasma free jet is investigated using spectrally narrow bandpass filtered high-
speed imaging. The images were captured at 16 kHz with an exposure time of 3.9 μs and …

Spallation is the mostly undesirable phenomenon where solid particles are ejected from
ablative materials leaving less mass to be decomposed at the ablator surface. The exact …

The hydrogen emission from meteors is assumed to originate mainly from the meteoroid
composition, making it a potential tracer of H2O molecules and organic compounds. H α line …

A method for assessing the performance of typical heat shield materials is presented in this
paper. Three different material samples, the DLR material Zuram, the Airbus material Asterm …

This article describes a novel high frame rate emission spectroscopy setup developed for
measurements in high enthalpy flow fields. The optical setup and the associated hardware …

The flow enthalpy of an arc-heated wind tunnel is an important parameter for reproducing
planetary entry and performing heating tests. However, its distribution is insufficiently …

The atomic translational temperatures and velocities of a low pressure, high enthalpy air
plasma are measured using Fabry–Perot spectroscopy. The measurements presented here …

The temperature of plasma jet is difficult to be measured directly because of its high
temperature. The heat flux is often used to measure the thermodynamic properties of plasma …
