AXIAL TURBOMACHINES WITH ROTARY HOUSING AND FIXED CENTRAL ELEMENT |
摘要 |
The invention is characterized by a rotary external housing and the attachment of the movable blades inside said housing, and by the attachment of the fixed (or static) blades to a shaft or other immovable central element, irrespective of whether compression and expansion occur in one or more stages. The proposed attachment eliminates radial play in the region that transfers maximum energy to the fluid, thereby drastically reducing the problems due to stalling at the boundary layer. In this way, there is no drop in the mechanical performance of small axial turbines and compressors with a less favourable ratio of radial play to diameter, an aspect that has prevented more generalized use thereof. The fixed blades, by not transferring energy to the fluid and decelerating the rotation thereof, encounter fewer stalling problems than the movable blades. |
