Constant Temperature Anemometry (CTA)
|
|
The CTA is a point-measuring technique appropriate
for the measurement of time series in one, two or three-dimensional gas and liquid flows. CTA is particularly suitable for the
measurement of flows with very fast fluctuations at a point (high
turbulence) and the study of flow microstructures, where there is a
need to resolve small flow eddies down to the order of tenths of a mm.
CTA is often applied in wind tunnel experiments during the design
phase of buildings and structures located both on land and in the
sea. These structures must be optimised to withstand interaction
with wind and/or wave forces.Typical applications include flows around tall buildings, bridges, offshore
oil rigs and research in aerodynamics and turbulence.

There are several types of CTA systems:
