In this paper, a numerical model was developed for direct simulation of droplet spreading behavior on the tablet edge since the coating unifonnity become the most critical problem nowadays in pharmaceutical industry. Owing to that problem, a simulation of droplet spreading behavior on the tablet edge has been developed to study the effect of tablet surface to the droplet spreading behavior. This modeling will be conducted by using integrated software, Computational Fluid Dynamics which is Fluent 14.0. Only water will be used in this modeling over to the different velocity of droplet. As addition, the surface roughness and contact angle also will be varying due to study the behavior of the spreading in certain condition. This project actually is the continuality of the previous laboratory experiment which is the study of the droplet impact behavior on the edge of a tablet to predict the coating variation, conducted by Ku Zilati Ku Shaari and Richard Turton from Department of Chemical Engineering, West Virginia University, Morgantown. The result of the simulation will be compared to this experiment result in order to have the clear understanding of spreading behavior on the tablet edge. As the result, there is not much different of the droplet spreading behavior between geometry I, geometry 2 and geometry 3 due to the very small change in the surface roughness applied to the wall. Theoretically, the smoothest surface will give the largest spreading factor, D;/ Do. Thus, further development and study on the model will be taken for the future work.
