Radial compressor i.e. transsonic radial compressor, for use in scientific research field, has shovel forward edge comprising profile and forming sweep angle with shovel upper edge, where forward edge is fixed at side turned away from hub
The compressor has a running wheel (1) comprising a hub (5) and main shovels (7) that are extended from the hub. The shovels are extended along radial direction of a shovel forward edge (13) and face away from the hub, where the shovel forward edge is formed in a shovel upper edge (15). The shovel forward edge comprises a wave-shaped profile and forms a sweep angle (17) i.e. acute angle, with the shovel upper edge. The shovel forward edge is forwardly fixed at a side, which is turned away from the hub. Pressure pulses are reduced before the shovels move with the wheel rotation.
