Side jets are ejections formed at the initial region of a jet. In recent experiments, it is confirmed that when the jet velocity is increased or decreased, a hysteresis phenomenon occurs in the side jets. That is, the value of jet velocity is different, when side jets are generated or disappear. It is expected that the phenomenon is related to the acceleration of jet velocity. Since an experiment for the effect of the acceleration on the side-jets formation is difficult, the aim of this study is to investigate the hysteresis phenomenon by a numerical simulation using open source software OpenFORM.
