Method and device for pressure jumps in two-phase mixtures

Device for increasing pressure in a two-component fluid mixture comprising;

• a. nozzle having an inlet, an outlet, a mixing section and a control section;
• b. means for supplying a first fluid component to said mixing section through said inlet of said nozzle;
• c. means for supplying a second fluid component to said mixing section of said nozzle such that it mixes with said first fluid component to form a two-phase mixture flowing with subsonic velocity;
• d. means for supplying a predetermined amount of a third fluid component to said control section of said nozzle so as to intermix with said two-phase mixture;
• e. expansion chamber coupled in fluid communication with said outlet of said nozzle for accelerating said intermixed fluid mixture;
• and
• f. outlet channel coupled in fluid communication with said expansion means, said outlet channel having a inlet of a cross-sectional area less than the cross-sectional area of the expansion chamber for accelerating said intermixed fluid to a supersonic velocity so as to create a pressure jump in said intermixed fluid.

• c. means for supplying a second fluid component to said mixing section of said nozzle such that it mixes with said first fluid component to form a two-phase mixture flowing with subsonic velocity, so as to increase the stagnation pressure of the two-phase mixture while decreasing its stagnation temperature;
• d. means for supplying at least one of a predetermined amount of a third fluid component to said control section of said nozzle so as to intermix with said two-phase mixture;
• e. expansion chamber coupled in fluid communication with said outlet of said nozzle for accelerating said intermixed fluid mixture;
