A REVOLVING ONE HOLE PROBE IN 2 D GAS FLOW FIELD

According to the velocity measurement principle of the three hole probe,a revolving one hole probe is proposed in this paper to realize the gas velocity amplitude and direction measurement simulaneously, and the corresponding measurement system is built up. The characteristics of this system is studied by experimental investigation, and find its use in various recirculating flows and swirling flows. The correct measurement principal, good repectability and high accuracy of this system are verified by the ...
