Abstrakt: Nozzles are devices generating jets. They are widely used in fluidics and also increasingly often in active control of flows past bodies. Being practically always a component of larger system, design and optimisation needs nozzle properties characterisation by an invariant quantity. Perhaps surprisingly, no suitableinvariant has been so far introduced. This article surveys approaches to characterisation quantities and presents several examples of their typical use such as parallel operation of two nozzles, matching a nozzle to its fluid supply source, apparent resistance increase in flows with pulsation, and the secondary invariants of a family of quasi-similar nozzles.
