    • A sealing device (122) for reducing fluid leakage between a rotor (104) and a stator (108) of a turbine apparatus (102) is disclosed. The sealing device (122) comprises a series of fluid inlet ports (132) such that a swirl component of fluid flow in a seal inlet region (134) impinges directly into inlet openings of the inlet ports (132), and a series of fluid jets (138) fluid into a leakage region so as to reduce the rate of leakage of fluid through the leakage region. A conduit (136) connects the inlet ports (132) to the jets (138). Kinetic energy resulting from a swirl component of motion of the fluid causes fluid in the conduit (136) to be at a higher pressure than in the seal inlet region (134).

    • 公开了一种用于减少涡轮机(102)的转子(104)和定子(108)之间的流体泄漏的密封装置(122)。 密封装置(122)包括一系列流体入口(132),使得密封入口区域(134)中的流体的涡流分量直接撞击入口(132)的入口开口,并且一系列流体 将流体(138)流入泄漏区域,以便降低通过泄漏区域的流体的泄漏速率。 导管(136)将入口端口(132)连接到喷嘴(138)。 由流体运动的漩涡分量产生的动能使导管(136)中的流体处于比密封入口区域(134)更高的压力。 公开了一种用于减少涡轮机(102)的转子(104)和定子(108)之间的流体泄漏的密封装置(122)。 密封装置(122)包括一系列流体入口(132),使得密封入口区域(134)中的流体的涡流分量直接撞击入口(132)的入口开口,并且一系列流体 将流体(138)流入泄漏区域,以便降低通过泄漏区域的流体的泄漏速率。 导管(136)将入口端口(132)连接到喷嘴(138)。 由流体运动的漩涡分量产生的动能使导管(136)中的流体处于比密封入口区域(134)更高的压力。
