Abstract

A novel anemometer was designed and implemented for simultaneous measurement of velocity and temperature in air flows with a single hot wire probe. The principle of periodically varying the overheat ratio of the wire was selected and applied through a parameterizable electronic chain. The specific methods developed for the calibration procedure and the signal processing are explained. The accuracy of the measurements has been assessed by means of Monte-carlo simulations. Examples of results are given for a non-isothermal low speed mixing layer. Finally the ability to extract velocity-temperature coupling in a turbulent non isothermal flow is highlighted through a conditional PDFs analysis.
