Abstract
A near-wall velocimetry probe includes a probe body configured for flush mounting on a surface, at least one tracer source mounted to or integrated within the probe body, at least one fiber bundle mounted to or integrated within the probe body, and at least one detector optically coupled to the at least one fiber bundle. The at least one fiber bundle is configured to capture optical signals from the tracers. The probe may include an illumination source embedded within the probe body and optical filters coupled to the fiber bundle. Methods for measuring near-wall flow velocity using the probe and systems for near-wall velocimetry are also provided.

A near-wall velocimetry probe, comprising:
- a probe body configured for flush mounting on a surface;
- at least one tracer source mounted to or integrated within the probe body;
- at least one tracer source configured to introduce tracers into a flow near the surface
- at least one fiber bundle mounted to or integrated within the probe body configured to capture optical signals reflected, scattered, or emitted from the tracers;
- and
- at least one detector optically coupled to the at least one fiber bundle, wherein the at least one fiber bundle is configured to receive optical signals reflected, scattered, or emitted from the tracers.
A method for measuring near-wall flow velocity, comprising:
- introducing tracers into a flow at a known location adjacent to a surface;
- collecting optical signals reflected, scattered, or emitted from the tracers using at least one fiber bundle positioned near the surface;
- and
- analyzing the captured optical signals to determine flow velocity near the surface.
A system for near-wall velocimetry, comprising:
- a probe body configured for flush mounting on a surface;
- a tracer source mechanism configured to introduce tracers into a flow near the surface;
- a plurality of optical fibers arranged in a pattern on the probe body to receive light from the tracers;
- and
- an imaging device optically coupled to the optical fibers and configured to capture optical data corresponding to tracer motion near the surface.
