Constant Temperature Anemometry (CTA) - Hot-Wire Anemometry - Thermal Anemometry
Measurement of turbulent flows
Constant Temperature Anemometry (CTA), also known as Thermal Anemometry, is a technique for the measurement of turbulence in 1, 2 or 3-dimensional gas and liquid flows, using hot-wire or hot-film probes inserted in the flow.
CTA is particularly suitable for the measurement of flows with very fast fluctuations at a point (high turbulence) and the study of flow micro structures, where there is a need to resolve small flow eddies down to the order of tenths of a mm.
| Measures velocities from a few cm/s to supersonic | High temporal resolution: fluctuations up to several hundred kHz |
| High spatial resolution: eddies down to 1 mm or less | Measures all three velocity components simultaneously |
| Provides instantaneous velocity information | Continuous analog output |
