Extract

In an early investigation of gas flow through a spool valve model Stenning discovered the same bi-stable flow patterns as had been established for oil flow, but reported no measurement of quantitative similarity or of other compressibility effects which would be of importance if such valves were to be used in pneumatic systems. Since then there have been no reports of comparisons between compressible and incompressible flow patterns in control valves, and the present investigation has been carried out to determine the characteristics of compressible flow through a two-dimensional model of a control valve port and to try to derive these characteristics from established compressible flow behaviour.
