Axial migration of spirulina microalgae in laminar tube flow.
A dilute suspension of Spirulina Microalgae is found to exhibit radial migration in laminar flow in a 650 micron vertical tube. As the tube Reynolds number increases, the particles concentrate in a narrower region around the tube axis. When the turbulent regime is approached, the particles disperse as expected.
