摘要： PROBLEM TO BE SOLVED: To provide a turbine having superior efficiency, by restraining a leakage flow of fluid to a downstream main cavity from an upstream main cavity.SOLUTION: In a turbine 1000, a seal member 1500 projected in a main cavity FMC generates the same flow separating vortex SSS in the same direction as a fluid main vortex FMS on a most upstream part end surface 1510, and generates a backflow separating vortex ASS in the opposite direction of the fluid main vortex FMS on a most downstream part end surface 1520. Since such the same flow separating vortex SSS and the backflow separating vortex ASS can restrain the leakage flow of fluid by the fluid main vortex FMS to the downstream main cavity MC from the upstream main cavity FMC, the efficiency of the turbine 1000 can be improved.
摘要翻译：要解决的问题：通过限制流体从上游主空腔向下游主腔的泄漏流动来提供具有优异效率的涡轮。解决方案：在涡轮1000中，突出在主腔FMC中的密封构件1500产生在大部分上游部分端表面1510上与流体主涡流FMS在相同方向上分离涡流SSS的相同流量，并且产生在最下游部分端面1520上与流体主涡流FMS相反方向分离涡流ASS的回流。由于分离涡流SSS和回流分离涡流ASS的相同流动可以抑制流体主涡流FMS向下游主腔MC流向上游主腔FMC的流体泄漏，所以可以提高涡轮机1000的效率。
