Effect of the volute casing on the flow in radial-flow blowers
Abstract
Using the assumption of inviscid and irrotational flow, a numerical method is introduced which makes the calculation of the flow field in a radial-flow blower possible. For a particular example, the influence of the geometry of the blower casing on the flow field in the casing is investigated. The details of the flow at the impeller outlet are discussed. The circumferential inhomogeneity of the flow properties at the impeller outlet suggest that vorticity and fluid viscosity may play an important role for the flow behavior in the blower.
