<p><P>PROBLEM TO BE SOLVED: To provide a fluid machine capable of effectively suppressing the occurrence of cavitation. <P>SOLUTION: The fluid machine 1 is equipped with a runner 2 formed by arranging a plurality of main blades 22, and a plurality of splitters 23 having wing length shorter than the main blades 22. A reference line o is drawn at a middle position of the pair of the adjacent main blades 22. At that time, the splitters 23 are disposed close to the main blades 22 side turning negative pressure surfaces to the splitters 23 more than the reference line o. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
