Drying analysis of particles (droplets) inside a spray dryer using the thermal fluid and powder analysis software "R-FLOW".
This is a case study of multiphase flow analysis that reproduces the process of droplets (fine particles) drying as they come into contact with high-temperature gas inside a spray dryer. The behavior, temperature, and evaporation rate of droplets injected from the top of the tank are analyzed using a discrete element method (DEM) model that incorporates a uniquely developed representative particle (coarsening) model. As drying progresses, the particles (droplets) gradually become smaller and either disappear within the tank or exit through the outlet at the bottom. Meanwhile, high-temperature gas flows in from the top of the tank and exits from the bottom. The concentration of water vapor in the gas is also analyzed. In the figure, the particles are displayed larger than their actual size.
