| Abstract: | This paper presents an experimental study of the internal flow field of a turbomachinery. It also discusses the problems arising with the application of hot wire anemometers to its measurements. A new formula has been developed for analysing the signals sampled by hot wires. The experimental results are satisfactory. |
