ABSTRACT:
A hydrokinetic amplifier 10 increases the vapor momentum transfer coefficient by directing an annular liquid jet 20 into an acceleration chamber 13 and impinging high velocity vapor streams on both the interior and exterior surfaces of annular liquid jet 20. Impinging merger of the inner vapor stream on the inner surface of liquid jet 20 transfers all the vapor momentum to the liquid. The outer vapor stream surrounding annular liquid jet 20 helps keep liquid out of contact with the acceleration chamber wall 19 and otherwise transfers a substantial portion of its vapor momentum to the liquid on which it impinges and condenses. Multiple annular liquid nozzles 11a and 11b and corresponding multiple vapor nozzles 50a and 50b can be arranged concentrically to capture all the momentum of the inner vapor streams, leaving only the outermost vapor stream to experience friction losses along the acceleration chamber wall 19.
