Using　air-to-water　film　two-phase　flow　test　equipment　with　a　high-speed　camera,　water　suction　from　the　suction　slot　in　front　of　stationary　blade　was　experimentally　carried　out.　The　water　film　moved　along　the　stationary　blade　surface　under　the　action　of　the　high　speed　airflow.　Under　the　suction　conditions,　the　tearing　of　the　water　film　at　the　trailing　edges　of　a　hollow　stationary　blade　were　studied.　The　results　show　that　the　water　film　flowing　on　the　stationary　blade　surface　would　immediately　break　into　some　silky　rivulets　or　sub-film　following　the　suction　slot,　if　the　water　in　the　film　was　partially　drawn　off　the　suction　slot.　The　silky　rivulets　or　sub-films　first　slightly　piled　up　at　the　trailing　edge　of　the　stationary　blade,　and　then　tore　into　drops　of　different　shapes　and　diameters,　and　moved　with　the　air　flow.　The　larger　drops,　formed　due　to　further　tearing,　broke　up　into　finer　droplets　due　to　the　action　of　high　speed　flow　air.　The　number　of　water　droplets　gradually　increased,　and　the　diameter　of　water　drops　gradually　decreased.　©　2005　Wiley　Periodicals,　Inc.
