This study presents results of tests on the structure of gas flow through a compressing stage of a radial blower. The tests conducted used LDA laser anemometer enabling measurement of velocities in diversified geometries such as, among others, geometries of the compressor rotors. The presented measurement results relate to a half-open axial and radial rotor, for which velocity field s were obtained in two control cross-sections, i.e. in the inlet cross-section and outlet cross-section. The obtained results enabled an evaluation of the effectiveness of the adopted design solutions.
