A new experiment to measure shocked particle drag using multi-pulse particle image velocimetry and particle tracking

We demonstrate the measurement capabilities for a new horizontal shock tube facility designed to measure the displacements, velocities and accelerations of shock-accelerated particles just after shock passage. Eight-frame particle image accelerometry and particle tracking velocimetry accelerometry diagnostics are implemented, along with a shadowgraphy system for measuring the shock location during experiments. We demonstrate the driving conditions of the facility using a unique membraneless pneumatic driver and particle seeding system that can accommodate both solid and liquid particles in the carrier phase. Measurements of two types of solid particles show unsteady drag forces higher than those for steady drag.
