Particle-Laden Flows

​

Introduction

• Common in nature and various engineering applications

• Typically involve two-way coupling with the flow

• Possible application, synthetic PIV of gas-phase detonation

• Particle Image Velocimetry (PIV)

  • ​Experimental particle seeding approach

  • Allows instantaneous flow field characterization

• Is PIV reliable for analyzing gas-phase detonations?

​

Research Details

• In depth study by numerically replicating PIV particles 

• Development of a coupled Lagrangian-Eulerian approach 

• Fully conservative formulation designed for fast compressible flows

• 2-D Hydrogen-air detonation

• Aluminum oxide PIV particles with realistic seeding density

• Massless tracers are seeded as PIV particles reach the detonation front

• Detailed analysis including:

  • Particle clustering

  • Trajectory accuracy

  • Effect on the flow field
