A 3D model was developed using COMSOL Multiphysics® to study the flow dynamics of the water inside the geometry of the [13N] Ammonia target for medical application . The image attached shows a 3D model of the target. A significant improvement was noted after modifying the geometry as suggested by the model and delivery time of radioactive solution was dramatically reduced. Water and aluminum were used as materials for, respectively, the channels inside and outer body of the geometry. The physics equations used to solve the problem of allocating proper place for the loading/unloading opening come from the Turbulent, k-ε Interface which is included in the CFD Module.
