Abstract
The method of investigation of the flow structure and correlation velocity/temperaturę fields in the LP stage using a CTA anemometer is outlined in the contribution. The arrangement of the rotary slanted hot-wire probe equipped with a resistance thermometer and pressure transducer is described that makes possible to correct the CTA-readings from the effect of the steam state small variations and from te disturbances caused by the impacts of large water droplets on the heated wire. Next some details of the synchronized sampling of CTA output voltage and the evaluation of the results are presented.
