N 1969, Tang presented an analysis of the flow through a choked axisymmetric nozzle. l The
following frequently used assumptions were invoked: I) the fluid is a perfect gas with …

The discharge coefficient of an axisymmetric contoured nozzle under steady, critical flow
conditions was studied theoretically and experimentally. In the aralysis, axisymmetric …

A class of critical nozzles, shaped according to the recommendation of the ISO Standard
9300, was selected for the present study. The flow in the nozzles was investigated …

Simple theory indicates that when critical flow of a gaseous fluid is established in a given
passage, the rate of mass flow becomes dependent only on the absolute pressure and …

For several decades critical nozzles have played an important role in flow measurement
science. These devices have been used extensively as gas flow transfer standards to …

Methods to calibrate a critical nozzle and a flowmeter against reference critical nozzles are
developed to replace the time-consuming conventional procedures. The discharge …
