ABSTRACT
As discussed in the preceding chapter, in the LagrangianEulerian approach a particle is numerically tracked throughout the simulation. Throughout the particle’s trajectory, it exchanges momentum with the local airflow. For a full CFD simulation, two-way coupling is normally adopted in which the airflow exerts a certain amount of drag on the particles, pushing the particle; at the same time, the drag effect also changes the momentum of the particle. A similar approach is adopted to numerically capture the drying process of the particle within the simulation domain. As the particle or droplet moves within the chamber, heat and moisture are exchanged with the local airflow contacting the particle. This is illustrated in Figure 5.1.
