Cfd Simulation of the Evaporation of Droplets in a Spray Dryer

The goal of this project is to build a Computational Fluid Dynamics CFD spray drying simulation technique. In this collaboration work with Formosa Plastics Corporation, the flow filed of the hot gas streams and the evaporation of droplets will be analyzed numerically. The relationship between the trajectories of the droplets and the local sintering at the surface of the dried products will be developed. The geometry and mesh of the pilot spray dryer will be built by ANSYS DesignModeler and ANSYS ICEM, respectively. The gas flow field and the trajectories of the droplets will be simulated using the commercial CFD software ANSYS-Fluent. The CFD simulation results will be validated by the temperature distribution measured inside the spray dryer by the cooperative company. The optimal operating parameters may be found based on the CFD developed relationship between the trajectories of droplets and the local sintering at the dried product surface. This project will enhance our understanding of the spray drying process and the process yields.
