CFD Simulation of Particle Residence Time in Small and Industrial Scale Spray Dryer

This paper presents a CFD study of short and tall spray dryers. The simulations were performed using turbulent model; standard k-ε (SKE), realizable k-ε (RKE) and the Detached Eddy Simulation (DES). The predicted axial velocity, temperature and humidity profile inside the spray drying chamber were f...
