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?
