A study of the flow in spiral-channel disks

Chemical and Petroleum Engineering Aims and scope

Two-dimensional flow is considered for a bladed ring with relative extent of the channel between blades less than 6. Hydrodynamic equations are used with an empirical formula for the hydraulic losses by friction in order to derive a general expression for the radial distributions of the axial and circumferential components of the flow velocity beyond the device without reverse flows at the input and counterflows at the output. The calculations are shown to agree satisfactorily with the experimental data.
