ablative-radiative TPS and Meteors

This study explores meteorite ablation using a free-piston driven expansion tube and a CW 4 kW fiber laser. Meteors, which are dust and rocks from comets or asteroids entering the Earth's atmosphere at high speeds (11.2 km/s to 72.8 km/s), emit light due to atmospheric compression and heating, occurring at altitudes of 80 km to 120 km. Analyzing their emission spectra can reveal their...

ablative-radiative TPS and Meteors

The study explores the impact of spectral radiative heat flux on material response by developing a coupling scheme between the KATS-MR code and a P1 approximation model for radiation transfer. A band model is created, dividing the spectral domain into small, unequal bands. Verification studies compare the band model’s results with pure conduction and the fully resolved radiative transfer,...
