• The volute of a centrifugal compressor serves to collect the peripheral mass flow from the radial diffuser. In almost all applications, limited installation space means that the design volume should be kept as small as possible. Moreover, smaller units lead to a considerable reduction in manufacturing costs. With regard to the volutes this leads to inwardly wound (internal) collectors, in which the volute cross-sections generally exhibit smaller radii than the diffuser outlet radius. This tight convolution leads to higher flow velocities and hence to greater losses compared with a larger, outwardly wound (external) volute. In this paper a comparison is drawn between experimental data for an internal and external volute. This comparison includes local flow phenomena as well as global changes of state, and also demonstrates major loss mechanisms.
