Reflected-type shock tube, equipped with laser absorption spectroscopy, is one of the most applicable facilities for experimental investigations in combustion kinetics. Ignition delay time of a specific fuel, as well as the products of combustion can be studied with a reflected-type shock tube. However, a minimum test time of 10 ms for test gas in designed pressure and temperature is required to investigate the combustion kinetics. A shock tube at “tailored condition” should be designed to produce a minimum test time of 10 ms with steady temperature and pressure. In this study, after a short review of the basic principles of a reflected shock tube, its design procedure is presented with the deigned stagnation temperature of 950K. Finally, the steady-state test time is measured to assure that the designed facility can provide the desired pseudo-steady thermodynamic conditions for combustion kinetic studies.
