Abstract—A new technic to measure the propagating flame precisely by using densely installed ion-probes has been developed. Densely installed ion-probes as grid shape are able to capture the propagating flame two-dimensionally along the confinement chamber wall. In the present paper, the characteristics of ion-current in propagating flame were investigated as a first step of the development. Secondary, characteristic features of this measurement technic were investigated. The series of basic tests for measuring the different types of propagating flame shows that the measurement technic has an ability to capture the fluctuation of propagating velocity in microscopic scale both in deflagration propagating at a few meters per second and in detonation propagating at supersonic speed.
Index Terms—Ion-current, signal amplification, flame propagation, detonation, micro explosion.
