A two-phase supersonic flow system.

摘要

A supersonic flow device for producing and maintaining a supersonic flow of a two-phase gas/liquid mixture and including a mixing chamber having an inlet (3) adapted to receive said mixture and an outlet (9) merging with a first end of an elongated neck portion, a second end of said neck portion communicating with an injector outlet, there being formed in an intermediate position of the neck portion a peripheral gap (15) which communicates with a housing chamber, said gap having a longitudinal axial dimension of the order of magnitude of the diameter of the neck portion. Preferably, the device is constituted by a supersonic two-phase flow injector and is formed with a housing (7) coaxial with the nozzle and having defined therein a liquid inlet chamber coaxial with and surrounding the nozzle, said mixing chamber merging at its inlet with said inlet chamber and converging towards its outlet. <IMAGE>
