Note on the Axisymmetric Sonic Jet.

Abstract

The axisymmetric jet exhausting to sonic pressure is considered, for simplicity, under the assumptions of transonic small disturbance theory. It is shown that the jet reaches its final state at a finite distance from the orifice. This result for the axisymmetric jet is thus the same as that for a jet. Part of the argument used to show that the jet reaches its asymptotic state is local in the hodograph. The result should also apply to a gas dynamic flow without the restriction of small disturbance theory. In the neighborhood of its final state disturbances from parallel sonic flow are in fact small.
