Calculation of rotor work on the basis of thermoanemometric measurement results. Part 1
(Wydawnictwa AGH, 2005) Fortuna, Stanisław
Article consists of two parts. The first part depicts results of calculations useful for the rotor work determination on the basis of thermoanemometric measurements and measurements of total pressure impact in given sections of the arrangement. Both measurements were made for one point of characteristic in the vicinity of optimal point, but for five different velocities of the rotor. The aim of the article was to verify both measurement methods and adjust results to the same conditions of flow.

Calculation of rotor work on the basis of thermoanemometric measurement results. Part 2
(Wydawnictwa AGH, 2005) Fortuna, Stanisław
In the second part of the article the correction of the balance method has been made by reduction of parameters to those sections where measurements of airflow velocity and the work determination were done. As losses of energy in supply line rotor between measure section and inlet as well as losses of energy in consequence of slot bypass leakage were taken into consideration, both methods of measurements gave the same increases of energy in the rim of rotor. Therefore, the methods may be considered as equivalent. The methods of field velocities and turbulence coefficient averaging were analysed with the aim to develop optimal measurement conditions.

Experimental verification of theoretical work of rotor
(Wydawnictwa AGH, 2006) Fortuna, Stanisław
The article presents results of the flow tests of a fan without casing based on calculations of increase of energy in rotor, efficiency and power on the drive shaft as well as thermoanemometric measurements behind the rotor. Results of the tests were compared with whirl work calculated analytically aiming at improvement of analytic calculations.
