The size distribution of silica particles as a model material from colloidal silica solution precursor in the flame assisted spray dryer method were studied numerically using Computational Fluid Dynamics (CFD). CFD has ability to solve the momentum, energy and mass transfer equation well. k-ε model was used to describe the turbulence model and non-premixed combustion model was used to combustion model. Collision and break-up model were also considered to predict the final particles size distribution. For validation, LPG with flow rate of 0.5?L/minute LPG and 200% excess air were used as energy sources. At this condition, numerical solution agreed well to the experimental work resulting in polydisperse size distribution. Therefore, others excess air, 100% and 150% were also observed using CFD and evaluated their contribution to their particles size distribution. Monodisperse particles size distribution were obtained when the combustion used 150% excess air.
