Methods and apparatus for measuring flow opening areas |
| 摘要 |
<p>The method involves positioning an illumination source e.g. laser (216), adjacent an opening (202) defined within a turbine nozzle. A perimeter that circumscribes the opening is illuminated by the laser. An image processor (226) samples an image of the illuminated perimeter. A nozzle throat opening area (213) within the received illuminated perimeter from the sampled image is calculated.</p> |
