This paper presents a CFD study on flow characteristics in the centrifugal fan in nominal and off-design conditions. Numerical calculations were carried out using ANSYS CFX package [10]. The numerical model was verified on the grounds of experimental tests using the standard methods to determine the performance curve of centrifugal fans. The following paper also presents the pressure distributions in select cross-sections of a machine, relative velocity, and static pressure profiles inside the rotor blade channels for the full range of flow characteristics.
