Turbine Fluid Velocity Field Measurement

摘要

A method of three-dimensional Doppler velocimetry applicable to turbines such as wind turbines achieves improved velocimetry by use of various possible convergent beam geometries and employing beam sources mounted on the turbine such as on a wind turbine nacelle, rotor hub or rotor blades.

主权项

1. A measurement system comprising:
a plurality of beam sources mounted on a turbine and arranged such that beams from the beam sources intersect at a measurement point; one or more receivers for measuring a Doppler shift of reflected or scattered beams; and a processor for determining a fluid velocity at the measurement point based on the measured Doppler shift.
