000012503 520__ $$2eng$$aPaper presents a new concept: invariants of second order. The idea bypasses the necessity of geometric similarity (allowing only scaling up or down) in working with dimensionless criteria parameters. Practical aspects of the approach are demonstrated on family of simple nozzles, with different lengths of exit channels. While fluid flow in each nozzle is characterised by its primary invariant, the family as a whole is characterised by additional two secondary invariants.
