In the present study, pre-processing program is developed which can model various geometry of a stirred vessel, and numerical analysis on improvement of mixing performance in solid-liquid mixing is conducted. The faster time and simpler method to model a stirred vessel with standardized
geometry is demanded to satisfy research environment in various industry. Then, this program can model various geometry of a stirred vessel linked with STAR-CCM+ that enable numerical analysis on flow field and mixing condition inside a stirred vessel. On the other hand, mixing condition of solid-liquid was numerically shown and specific condition of geometry of a stirred vessel and
operation can be suggested to improve mixing performance. Simulation of solid-liquid mixing was conducted with STAR-CCM+ to predict flow pattern
and behavior of particle. Lagrangian method is used to track all of individual particle. For the better accuracy of simulation, PIV experiment that visualizes two-dimensional flow field inside a stirred vessel is conducted and compared with result of simulation. Inter-particle distance is originally developed in this study to evaluate and quantify condition of solid-liquid mixing with difference
parameters. This inter-particle distance is averaged value of distance between one particle and its nearest particle in limited volume of a stirred vessel. Therefore solid-liquid mixing is analyzed with particle suspension and istribution linked to flow pattern formed by various agitating conditions.
