Abstract
A solid-liquid two-phase mixture (water and aluminum particles) is horizontally led to a T-junction. The particle number densities (number of particles per volume) at the outlets are measured in the inlet concentration of (0.9-16.8) ×10-3%, at the velocity ratio of the outlet to the inlet as the parameter. The diameter of tube in the T-junction is 10 mm, Stokes number ranges with 0.14 to 6.6, and liquid Reynolds number ranges with 9300 to 13000. The relationship between the particle number densities in the two outlets is obtained by a one-dimensional model. We compare the measured particle number density in the branch with the concentration obtained by Nasr-El-Din whose inlet concentration is 3 to 26%. The followings are obtained. The one-dimensional model can express the relationship between the concentrations of the two outlets. The present distribution characteristics of the T-junction show the same tendency as Nasr-El-Din's. However, the gradient of particle number density with respect to velocity ratio for the low concentration at the inlet is greater than that for high concentration data.
