Abstract
An ultra-high speed, time-resolved particle image velocimetry (PIV) system is developed to measure velocity fields created by explosive detonators. When initiated into a gas, the detonators generate blast waves that propagate outwards from the origin of initiation at supersonic speeds. The PIV system consists of a custom eight-pulse Nd:YAG laser system and an ultra-high speed camera system comprising four dual-frame CCD cameras optically combined to share a single optic axis. The system is capable of sampling the flow field four times at up to 333 MHz or eight times at up to 8 MHz. System development is discussed, and preliminary application to the complex flow behind the blast wave from an exploding bridge wire detonator is demonstrated.
