In order to obtain fundamental knowledge of liquid breakup phenomena, the three dimensional flow field of oscillatory liquid jet in pinch off was numerically studied by the developed method, CIP-LSM. In the present paper, not only the liquid jet shape but also its inner structure was investigated. The numerical results of liquid shapes and velocity distributions were compared with the corresponding experimental ones. From the results, CIP-LSM was confirmed to have potential to simulate liquid breakup phenomena in which surface tension was predominant. It was revealed that inner structures of the liquid jet were constructed due to the surface tension at the nozzle exit. The jet breakup was demonstrated to occur at the fluid element injected with the minimum acceleration.
