FIELD: machine building.
SUBSTANCE: invention relates to devices intended for visual demonstrations and studies of aerodynamics of profiles during laboratory work and experiments on studying the flow structure in blade channels. Installation for investigation of flow around blades of a blade diffuser of a centrifugal compressor comprises a frequency converter, an asynchronous motor electrically connected to the frequency converter; centrifugal fan located in the volute of the centrifugal fan; honeycomb section rigidly connected to the volute of the centrifugal fan; main working section, which is a hollow transparent housing, rigidly connected to the honeycomb section, in which the diffuser sectional model blades are placed, digital hot-wire anemometers configured to be placed in measuring planes in the honeycomb section and at the outlet of the main working section.
EFFECT: improved clarity of processes when demonstrating and investigating aerodynamics of profiles.
