Radial thrust current is one of the centrifugal compressor characteristics. Air enters the rotating impeller’s center through the radial blades and flows outward by the centrifuge force to the rotating impellers area. Before entering the next rotating impeller’s center, air passes through a diffuser and a snail compartment in which the kinetic energy changes into static pressure. The proportion of the pressure in each stage determines the total pressure of the compressor. After each impeller’ rotation, the air pressure also increases significantly.
