ABSTRACT:
In the present invention separation is effected by means of a convergent-divergent nozzle, in which the divergent portion is convex. A supersonic flow of a gas-droplets mixture is introduced into the convergent-divergent nozzle and at the throat thereof a normal shock wave occurs and results to an abrupt change in the speed and direction of gas flow, which becomes subsonic and follows the geometry of the convex divergent portion. The droplets are inertially separated from the gas stream and two flow zones emerge, one zone free from droplets and one enriched with droplets, these two zones being subsequently separated by a separator plate. Henceforth, a conventional subsonic separator is used to receive the liquid formed by the separated droplets, whereas the zones of gas flow being free from droplets converge to be subsequently used in any desired manner.
