ABSTRACT:
A fluid mover (1) includes a passage (3) of substantially constant cross section into which supersonic steam is injected through an annular nozzle (16) as a transport fluid to contact a working fluid, e.g. a liquid, to be treated, the passage further including a mixing chamber (3A) downstream of the steam injection where the mixture is accelerated upon the creation of a low pressure zone occasioned by the condensation of the steam, a dispersed droplet regime and a shock wave being generated downstream of the nozzle (16). A pseudo-convergent/divergent section is created and provides a flexible boundary in the absence of physical constraints to yield an improved performance by combining shear dispersion and/or disassociation with the effects of the shock wave. The fluid mover (1) may be used in a wide variety of applications for pumping, heating, mixing, disintegrating, classifying and separating among others.
