ABSTRACT:
A directed, high-velocity stream of compressible fluid is produced and put to use (as in a turbine) by adding heat to such fluid as it flows through and expands within an elongate nozzle prior to discharge therefrom but following passage through a throat of such nozzle. The fluid is supplied to the nozzle at pressure greater than the atmosphere into which the high-velocity stream is directed and discharged. Apparatus for carrying out the method of the invention comprises one or more elongate nozzles, each having a throat and constructed with means for adding heat to fluid flowing from such throat toward the nozzle outlet through an elongate discharge portion of the nozzle having flow passage of effective cross-sectional area that gradually increases from the nozzle throat to the nozzle outlet. A preferred form of the apparatus includes an elongate center unit which converges from end to end thereof and is positioned within the discharge portion of the nozzle in spaced relationship with the walls thereof and with its larger end adjacent to the nozzle throat and its smaller end adjacent to the nozzle outlet, so as to divide flow of fluid through such discharge portion.
