Post-detonation fireball thermometry via 1d rotational cars

Richardson, Daniel R.; Kearney, S.P.; Guildenbecher, Daniel R.

The temperature inside fireballs produced by detonations is an important quantity of interest for the validation of models. However, such measurements are very difficult to make due to the large pressure and temperature gradients and the harsh environment. In this abstract we will report on one-dimensional rotational coherent anti-Stokes Raman scattering (1D RCARS) measurements performed in such fireballs. CARS measurements were performed at 18 and 28 µs after detonation of a commercial detonator, and the measured temperatures are in the range 300–1600 K.
