Mixing behavior of multiphase turbulent flow in a jet bubble column is studied numerically. For the two-phase flow, air and water are used. The solids and liquid are assumed to form a pseudohomogeneous slurry phase, in the three-phase studies. The time evolution of the mixing behavior of a liquid tracer is considered in turbulent flow within a jet bubble column. Some of the predictions of the numerical model, for the two-phase flow, are compared with experimental measurements. Measured Residence Time Distributions (RTD) of the liquid tracer within the cone agree well with the predicted values given by the numerical model. For the range of parameters considered in the study, lack of radial mixing is evident within the column which axial mixing is found to be large. Lack of mixing is observed near the walls of the column. Three phase flow study is under investigation.
