Hot-Wire Analysis of a Turbulent Jet

Hot-wire anemometry is used to measure a turbulent jet and study its fast changes in speed. Turbulent flows have very high-frequency fluctuations, so they require instruments with a fast time response for proper measurement. A hot-wire anemometer has that short response time and can capture these rapid velocity changes.

Turbulent flows play an important role in a wide variety of engineered and naturally-occurring systems. As a result, it is often necessary to perform measurements within the system in order to characterize the flow. Turbulent flows exhibit very high frequency fluctuations so any instrument that is used to measure and characterize turbulence must...
