A series of experiments were performed on the fan-shaped water mist interaction with the horizontal under-expanded hydrogen jet flames. The effects of various water mist pressures and horizontal release positions were focused on flame length, temperature, and radiant heat flux. The results show that, water mist causes the flame to be tilted and the tilt angle of the flame increases with the water mist pressure, and the horizontal length of the flame is shortened. It is also found that water mist may lead to the radiation and temperature enhancement on the axis and downstream of the action position of water mist and flame, which is closely related to the configuration of water mist. However, this situation disappears and the temperature and radiation decrease with the increase of water mist pressure.

对扇形细水雾与水平欠膨胀氢喷射火焰的相互作用进行了一系列实验。各种细水雾压力和水平释放位置的影响主要集中在火焰长度、温度和辐射热通量上。结果表明，细水雾使火焰发生倾斜，火焰的倾斜角随着细水雾压力的增大而增大，火焰的水平长度缩短。还发现细水雾可能导致细水雾和火焰作用位置的轴线和下游的辐射和温度增强，这与细水雾的构型密切相关。但这种情况消失了，温度和辐射随着细水雾压力的增加而降低。
