Results of the centrifugal fans research project including CFD simulations of the relative velocities, trajectories and pressure profiles inside the rotor blade channels, have been presented in this study. Complete analysis of the characteristics was performed. Theoretical analysis of one-dimensional flow has also been studied. The conclusions confirmed that the change of rotation direction of the relative vortex inside the rotor blade channels, occurs along the fan characteristic.
