The work describes sand-particle high-Reynolds number flow in a Tjunction. Experiments are carried out for one different Reynolds number (Re = 9.5x104), one typical particle diameter distribution (Mesh 150) and four sand concentrations (0.05, 0.1, 0.6 and 1.1 % w/w). The purpose of the work is to characterize the effects of indirect particle-to-particle interaction as particle load increases. PTV and PIV measurements are used to discriminate the velocities of the particles and the carrier fluid. The results shown that rebounding effects have a significant influence on particle dynamics.
