Note (General): This paper is concerned with a numerical method and its application to the prediction for turbulence structure which is induced in three-phase flows containing bubbles and particles. The Eulerian-Lagrangian model for three-phase flows has been constructed since the mathematical validity of the model was confirmed for bubbly two-phase flow in previous papers. Two-and three-dimensional predictions were carried out and provided detailed phenomenological information on three-phase interaction processes. When the bubble and the particle volume fractions were less than 5%,generation of kinetic energy was reduced more in three-phase flow than in two-phase flow,because of decrease in body force spectrum. Especially,the turbulence with long wave length was not strongly grown because of cancelation of meso-scale body force due to local dispersion of the bubbles and the particles. Resultant slope of energy spectrum in high wavenumber region became much calmer than the similar phenomena in bubbly two-phase flow cases.
