Abstract:

The object of our experiments is to develop photothermal deflection spectroscopy PTDS into a technique capable of measuring minority species concentration, temperature, and flow velocity, simultaneously in a flame. We have demonstrated the simultaneous measurement of relative OH concentration, temperature, and flow velocity in an H2O2 flame using saturated PTDS. By working in the saturation regime, relatively large signal-to-noise ratio is obtained, and effect of pulse-to-pulse energy fluctuation is minimized. In the next period we will try to obtain absolute concentration measurements, along with the temperature and the flow velocity.
