Nozzle discharge coefficient determination at non-steady gas efflux from a receiver

Abstract

An empirical method is suggested for obtaining of the stabilization time for the QSF regime of the efflux from a receiver at sudden diaphragm opening, and also the dependence for the mass flow rate through the nozzle during the transient. Besides, the given method allows one to obtain with controllable accuracy the nozzle discharge coefficient.
