Patent ID: 8387956

Claim:
A method, comprising: injecting a vapor phase of a liquid material through a first nozzle into a cooler liquid phase of the material to provide a boiling hot liquid flow in a mixing chamber downstream of the first nozzle, feeding the hot liquid flow through a convergent section of the mixing chamber causing acceleration of the hot liquid flow to a supersonic velocity and obtaining a volumetric gas-to-liquid ratio of at least about one-third; discharging the hot liquid from the convergent section into a constant cross-section channel leading into a divergent part of a second nozzle to cause deceleration of the hot liquid to a subsonic velocity with a sudden change of pressure, reduction of the volumetric liquid-to-gas ratio to less than about one-third and heating of the hot liquid flow, converting the flow to a homogenous isotropic liquid with entrained microscopic vapor bubbles; and accelerating the flow through a second nozzle to cause a second boiling of the hot liquid flow obtaining a volumetric gas-to-liquid ratio of at least about one-third with acceleration of the hot liquid flow to a supersonic velocity at an outlet of the second nozzle.
