 note = {[synopsis] This paper is a research development about the design of atomization nozzles that manufacture the minute metal powder used in an industrial field. The purpose of study is to clarify the influence of exit shape of an annular nozzle on the flow fields of an annular supersonic jet. This paper has clarified a gas-liquid two-phase flow issued from an annular nozzle to research and develop a practicable nozzle. Especially, the gas-liquid two-phase flows for the air-molten aluminum have been clarified by the numerical analysis. Finally, the velocity, pressure contours, and the FVF of the flow on the effects of an annular supersonic jet on the minute powder of the air-water or air-molten aluminum are examined. As a result, it is clarified that the flow fields of a gas-liquid two-phase flow of the nozzle exit are influenced considerably by the configuration of molten metal nozzle exit and the stagnation pressure. Moreover, the fluid volume fraction (FVF) of the molten aluminum is examined, and according the breakup mechanism of minute aluminum powder is clarified., application/pdf},
