A solid-liquid two-phase mixture (water and aluminum particles) was vertically led to a T-junction. Particle number densities (number of particles per volume) at the outlets were measured, at inlet concentrations of (1.7〜9.2)×10^<-3>%, Reynolds number ranging from 12000 to 19000, and Stokes number of 0.45 to 4.3. As a result, we found a velocity ratio (branch velocity/inlet velocity) range where solid particles did not enter the branch of the T-junction with the vertical orientation. The present data at lower inlet concentrations was compared with those obtained by Nasr-El-Din at higher inlet concentrations, i.e., 3 to 26%. We found that dimensionless concentrations at the branch (the present data) were higher than those obtained by Nasr-El-Din. Our dimensionless particle number density at the branch for the T-junction with the vertical orientation was found to be higher than those with the horizontal T-junction at similar inlet concentrations.
