Study of gas-solid two-phase mixtures has been performed recently in many different ways. One of the ultimate purposes of this study is to prevent dust explosion accidents. The present study focuses on experimentally measuring ignition delay times to provide data for numerical analyses. Experiments are performed using a vertical shock tube to ignite the reactive dust layer on the bottom of the tube by a high temperature and high pressure condiction behind a reflected shock wave. Cornstarch dusts are selected as reactive dust particles. Ignitions of the dust particles are detected and ignition delay times are also measured. These values agree well with the published data to the Arrhenius plots as far as the similar experimental system is concerned.
