Correction of hot-wire anemometer measurements in high turbulent flows

A flow model is described which was developed in order to describe the problems which arise in such measurements. It is shown that in contrast to known approximate solutions the errors can be found over a wide range of velocity with high accuracy, and corrections are available. The accuracy of the t...

Zusammenfassung:A flow model is described which was developed in order to describe the problems which arise in such measurements. It is shown that in contrast to known approximate solutions the errors can be found over a wide range of velocity with high accuracy, and corrections are available. The accuracy of the turbulence model is proven by appropriate measurements which allow a more accurate interpretation of hot wire signals. Further, the range of application is extended to higher intensities of turbulence, and it is shown that the measurement errors, generally, can be corrected even in this range.
