Background
The centrifugal fan accelerates gas by using an impeller rotating at a high speed according to the principle that kinetic energy is converted into potential energy, and then decelerates and changes the flow direction so as to convert the kinetic energy into the potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from an axial direction, changes to a radial direction as it flows through the impeller, and then enters the diffuser. In diffusers, the gas changes direction of flow and the increase in duct cross-sectional area slows the gas flow, which converts kinetic energy into pressure energy, with the pressure increase occurring primarily in the impeller and secondarily in the diffusion process. In a multistage centrifugal fan, a flow reverser is used to direct the air flow to the next impeller, creating a higher pressure.
