Numerical Simulation of Spray Drying of Pulsating Flow Generated by a Pulse Combustor

Spray drying generated by a pulse combustor was simulated using the computational fluid dynamics method. The simulated profiles of flow field and particle locus, local temperature and humidity of the air phase in the drying chamber were presented and the drying process of the particles with different initiate diameters was analyzed. The simulation results show that the short drying time and large evaporation rate are characteristics of the pulsating spray drying.
