Hot-wire Anemometry and Planned Test Entries- Hot-wire anemometers are sensitive to mass flux and total temperature
- Applications for hot-wire anemometry include
- Determining the flow quality within a facility
- Mapping the flowfield that is influenced by a model
- Mean flow distortion
- Boundary-layer instabilities & transition
- It’s an especially important diagnostic if there is no line of sight
- We use a constant temperature anemometer (CTA) at a high overheat & calibrate the wire using a modified King’s Law
