VORTEX IDENTIFICATION METHODS AND TOOLS |
| 摘要 |
A vortex detection method is described. The method comprises storing a plurality of points at locations over a region (32) in which vortex detection is to be performed. A value for each of a plurality of fluid flow parameters, such as velocity, pressure and density, is determined at each point. The points are grouped as being contained in either a vortical flow portion or non-vortical flow portion of the region according to one or more statistical distribution for said fluid flow parameters. A point (p) in a vortex core is identified according to the direction of motion of an array of further points (46) relative to said point in the vortex core. The further points (46) may surround the vortex core point. |

1. A vortex detection method comprising:
identifying a plurality of points at locations over a region in which vortex detection is to be performed, storing a value for each of a plurality of fluid flow parameters at each point, grouping the points as being contained in a vortical flow portion or non-vortical flow portion of the region according to one or more statistical distribution for said fluid flow parameters, and identifying a point in a vortex core according to the direction of motion of a plurality of further points relative to said point in the vortex core. |
