Abstract
A two-phase nozzle having a converging diverging configurations is equipped with a flow divider at its inlet. The flow divider is arranged to act upon an incoming flow of two-phase liquid to break the liquid phase into finely divided droplets which are directed into the nozzle entrance region so that minimum contact is made with the inside wall of the nozzle. The finely divided droplets are thus thoroughly dispersed in the gas phase of the mixture producing maximum acceleration of the fluid through the nozzle.
Claims15
Apparatus for increasing the acceleration of a two-phase working substance through a nozzle that includes
- a two-phase nozzle having an entrance for receiving a flow of a two-phase working substance and expanding the working substance to a lower pressure to convert at least a portion of the energy in the flow to kinetic energy,
- a flow divider connected to the entrance of said nozzle for directing said two-phase working substance into said nozzle,
- said flow divider having means for separating the liquid phase of the working substance in the flow from the gas phase and dispersing the liquid phase into finely divided droplets, and
- said flow divider further including means for directing the droplets inwardly toward the central axis of the nozzle.
A compression/expansion refrigeration apparatus which includes a fill of two-phase refrigerant,
- a rotary compressor having an input shaft that is coupled to a drive motor and to a turbine expander for compressing refrigerant to a high pressure, whereby the refrigerant leaves the compressor in a vapor state,
- a first heat exchanger connected between a compressor outlet and a turbine expander inlet for condensing the refrigerant wherein the refrigerant leaves the first heat exchanger at about saturation,
- a two phase nozzle mounted at the inlet to said turbine expander for guiding the entering two phase mixture to a lower pressure to convert some of the energy in said entering mixture to kinetic energy,
- flow divider connected to the entrance of said two phase nozzle having means for separating the liquid phase from the two-phase refrigerant flow prior to the flow entering the nozzle and dispersing the liquid phase into finely divided droplets to accelerate the flow of refrigerant through the nozzle, and
- a second heat exchanger connected between the turbine expander outlet and the compressor inlet wherein the refrigerant is further expanded prior to entering said compressor.
