About This Lesson
- This work presents a CFD–DEM simulation of a rotary seed dryer.
- Hot air flows through the inclined drum at 350 K while the drum rotates at 20 RPM.
- Seeds are modeled with the Discrete Phase Model (DPM) coupled with evaporation into H₂O vapor. The Discrete Element Method (DEM) accounts for particle–particle and particle–wall collisions, improving realism of seed motion.
- Contours of H₂O mass fraction reveal zones of strong evaporation, reaching values up to 0.0026.
- The combined CFD–DPM–DEM approach shows how airflow, fin mixing, and collisions enhance drying efficiency.
