TL;DR
This paper investigates UV radiation emitted by nitrogen in a shock focusing facility, comparing experimental measurements with SPECAIR simulations to identify emission sources and estimate gas temperature.
Contribution
It provides experimental data on UV radiation in shock focused nitrogen gas and validates SPECAIR software for emission analysis at high temperatures.
Findings
Radiation matches N2+ Meinel transition emissions.
Estimated gas temperature around 6000K.
Experimental results align with SPECAIR simulations.
Abstract
A study on UV radiation in shock focused gas has been carried out in high temperature radiating Air experimentally. Spherical shock wave focusing was achieved with the help of a contoured converging section attached to a shock tube. The measured radiation is compared with SPECAIR software to find out that the radiation corresponds to the emission of N2+ Meinal transition. The temperature of the radiating gas was estimated from SPECAIR and was found to be around 6000K.
