To investigate the effect of the axial airflow on the primary breakup of axisymmetric dissemination, a set of new facility is designed. It’s composed of two shock tubes, a set of electronic synchronous equipment and a schlieren optical system. By using these facilities, many schlieren photographs of the axisymmetric dissemination, breakup and atomization of the liquid under the action of axial airflow were obtained. From these photographs, it can be found that the liquid core of axisymmetric dissemination has two stages: the core growing stage and the core stable stage. It can also be found that there is a turning point at the boundary of liquid dissemination. This turning point can be regarded as the position where the primary breakup takes place. From the comparison of positions of the primary breakup, it can be concluded that the axial airflow can greatly enhance the primary breakup of axisymmetric dissemination.
