<p><P>PROBLEM TO BE SOLVED: To provide a turbine improving turbine performance by efficiently reducing leakage of fluid from a clearance between the rotor blades of the turbine and a casing. <P>SOLUTION: This turbine 1 includes: a shaft body rotating around an axis; a plurality of rotor blades 50 arranged in a peripheral direction on the peripheral surface of the shaft body; the casing 10 formed to surround the rotor blades 50; and a plurality of stator blades arranged in the peripheral direction on the inner periphery of the casing 10 on the upstream side of the rotor blades 50 in the casing 10. The turbine is so configured that fluid passed through the stator blades is passed through the rotor blades 50. A seal member 17 is formed for suppressing leakage of the fluid from the clearance Gd formed between the rotor blades 50 and the casing 10. On the upstream side of the seal member 17 in the clearance Gd, a circumferential flow baffle 70 for generating a pressure loss in the fluid passed through the stator blades and reducing total pressure extends to the inner peripheral side of the casing 10. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
