In order to design a swirl generating system on the sodium handling training center of the fast breeder reactor training center, swirl generating behavior in a closed room was studied experimentally, and the following results were obtained. Since the inertia force is dominant in swirl generating. Froude number (Fr) and the swirl Froude number (Frc) which are the ratio of the inertia force and gravity are important factors. The air supply flow rate with which the size ratio of a model test the system was altogether satisfied of Fr similarity and Frc similarity in the same conditions is equal to the 2.5th power of a size ratio. From the tests results, the swirl generating conditions of Fr and Frc are clarified, and it has checked that the prediction of the swirl generating characteristics of the system could be carried out by model examination of Fr and Frc similarity.
