Accurate determination of the flow rate through pneumatic devices and
components is essential to the design and optimization of industrial
equipment using these components. Indeed, the complexity of current
approaches remains a barrier to their understanding, therefore, their
generalization. This issue often occurs in pneumatic power transmission
and also in the compressible fluid control valves. It is however important
for all the users to be familiar with the methods used to determinate the
flow rate characteristics of the installed devices. A theory taking into
account the compressibility of the fluid was developed in several prior
works; they allow characterizing the flow through any device by
considering the choked and the unchoked flow. The methodology developed in
the literature needs at least two coefficients: critical pressure ratio
and flow rate coefficient. From a theoretical development, and subsequent
simplified theory, this publication (9Q193) provides a simple method to
calculate flow coefficients and the critical pressure ratios for all
pneumatic components condidered separately or as an assembly, in
compressible fluid when the flow is assumed to be adiabatic. An exhaustive
experimental study is conducted to verify the assumptions made here and
validated the theoretical results.
