Visualization and Measurement of Mixing Process of Particles Into Water Jet

A mixing process of catalyst particles into a fluid jet is a key part in a chemical reactor because the efficiency of chemical reaction depends on the particle catalyst distribution. Therefore, a mixing process of polystyrene particles into a water jet was investigated experimentally as a basic study of flow with catalysts in the chemical reactor. The velocity fields of both water and particles were measured by image processing. The main results obtained are as follows. The particle velocity approached to the water velocity at the mixing process, when the particles were entrained into the water jet. Because the particle concentration was very low, the velocity distributions were not changed by the addition of the particles. However, the turbulent intensity of the water increased comparing with the case of the water single phase jet.
