Experimental determination of the fluid velocity by spectral analysis of temperature fluctuations
Abstract
Local velocities of turbulent closed channel flow were measured applying the noise analysis technique to signals coming from two sensors separated by a known distance. Good agreement was found when comparing experimental data to more accurate measurements. Ranges of Reynolds number and thermocouple spacial separation are recommended.
