Experiments were carried out to understand burning behavior of a falling liquid sodium drop and to get verification data for an analytical program. The main results of this research were as follows. (1)Design and manufacturing of experimental devices. Devices were designed and manufactured, which generated liquid sodium drops with diameter of 3.51.0 mm and with temperature of 500 10C and dropped them in the atmosphere of inert gas and air. (2)Measurement of liquid sodium drop diameters of the inert gas experiments. Four experiments were conducted, in which 50 drops of liquid sodium were fell into inert gas atmosphere. An averaged diameter of liquid sodium drop was about 3.8 mm. (3)Measurement of burned weight and drop velocity of the air atmosphere experiments. Six experiments were conducted, in which 50 drops of liquid sodium fell into air atmosphere. An averaged burned weight of the liquid sodium drop was about 3.4 mg. The velocity after about 2.4 m drop was evaluated from photographs. Which indicated that the falling velocity of burned and un-burned single liquid sodium drop was 5.5 0.1 m/s.
