Using some simple assumptions with regard to the boundary conditions and confining the considerations to flows with small Rossby numbers, a pattern of streamlines corresponding to an axial plane of an incompressible vortex flow in a cylindrical vortex chamber is computed. The pattern obtained agrees qualitatively, in the main regions, with velocity profile measurements and dye-injection flow visualization experiments.

Moving Parts

Flow control problems in combined sewerage systems can be solved with the aid of a new variation of the vortex amplifier. This valve has no moving parts, and comes under the category of pure fluidics; it has a conical vortex chamber and a single inlet port. Depending on the level of water in the vortex chamber the flow pattern may be either axially symmetrical or axially asymmetrical. This effect enables the device to alter its flow resistance in response to the input pressure. Several hundred of this type of the flow controller are already in operation. An example of their application is described below.

Momentum Integral

Because of the characteristically narrow impeller tip width in a proposed supersonic centrifugal compressor design, boundary layer effects in the vortex chamber are likely to be significant. The radial pressure gradient in the chambers sweeps retarded fluid towards the centre of curvature of the streamlines, thereby creating a ‘cross-flow’ in the boundary layer which is three-dimensional. Although the flow geometry has axial symmetry, the cross-flow is not independent of the streamwise flow. The momentum—integral method is adopted, together with assumptions concerning the velocity profiles; the energy equation is solved with the assumption of an adiabatic wall. Simultaneous solution of the free stream and boundary layer equations yields results emphasizing the critical dependence of the transverse deflection and growth of the boundary layer on the whirl component of the velocity. Separation cannot be predicted, but effects in the free stream can be estimated when the perturbations are small. Although the results are related to compressor performance, the method is generally applicable in situations where the idealizing assumption of spiral vortex flow is acceptable.
