Measuring Turbulent Flow with Hot Wires

Description

Hot-wire anemometry measures fast changes in fluid flow with a thin heated wire. Its very short time response makes it useful for rapidly fluctuating motion, especially turbulent flows.

This experiment demonstrates how hot-wire anemometry is used in practice. It shows a method for tracking flow c...

Transcript

Hot wire anemometry is a common experimental technique for measuring fluid velocity during flow tests. Velocity is often an important parameter of the flow to characterize. But as with many flow properties, it is challenging to measure without impacting the experiment. Measurement of turbulent flows adds an additional complication, since the vel...
