Background:

Particle aggregation in fluid flows is crucial for understanding complex systems.
Microfluidic devices offer controlled environments for studying such phenomena.

Purpose of the Study:

To investigate the formation of particle aggregates in a microfluidic device.
To characterize the morphology and formation conditions of these aggregates.

Main Methods:

Introducing polyacrylamide (PAM) solution and polystyrene (PS) beads into a microfluidic channel with micropillars.
Observing and quantifying particle aggregation under varying flow regimes.

Main Results:

Formation of thin, slender particle aggregates (streamers) tethered to micropillars.
Identification of specific flow regimes leading to streamer formation using state diagrams.
Streamer formation is linked to the flocculation of PS beads.

Conclusions:

Streamer formation is a novel phenomenon observed in particle-laden microfluidic flows.
Understanding streamer formation provides insights into particle-laden complex flows through porous media.
