Chemical kinetics studies at high temperatures using shock tubes

Abstract

Shock lube is an unique facility to create temperature gradients exceeding million degrees Kelvin per second. We have established two shock tubes for measuring the kinetic reaction rates at high temperatures with two different but complementary detection techniques. The first one is a single pulse shock tube. in which the reflected shock is used toheat the molecules. The equiliberated products are analyzed by gas chromatograph and infrared spectrometer. The second one uses laser-schlieren system for online monitoring of the chemical reactions behind primary shock wave.The details of the shock tubes and some typical results obtained are presented in this paper.
