Definitions
- Nozzle capable of maximizing the amount of movement produced by a two-phase flow coming from the expansion of a saturating flow
- the invention lies in the field of ejectors and nozzles used as expansion members in turbines.
- these devices are designed to convert the energy of pressure into kinetic energy, this kinetic energy being used to produce a work, for example to rotate augers, turbine blades or, in the case of ejectors , to suck a flow.
- Figures 1 to 4 illustrate this phenomenon.
- Figure 1 shows a nozzle 1 according to the state of the art.
- This nozzle 1 comprises a convergent 2, a neck 3, and a moderate angle divergent 4.
- a saturating liquid flow D enters the nozzle 1 through the convergent 2, and travels this nozzle from right to left through the neck 3 then the moderate divergence 4.
- FIG. 2 shows the abscissa of the measured pressure of the flow rate D during its course in the nozzle 1 of FIG. 1, and the ordinate the mass velocity pV, product of the density p by the velocity V. Note that this mass velocity is maximum at the neck 3, (marked by the vertical line).
- FIG. 1 shows a nozzle 1 according to the state of the art.
- This nozzle 1 comprises a convergent 2, a neck 3, and a moderate angle divergent 4.
- a saturating liquid flow D enters the nozzle 1 through the convergent 2, and travels this nozzle from right to left through the neck 3 then
- FIG. 4 represents the evolution of the speed (V, expressed in m / s) of the flow rate D as a function of the pressure (P, expressed in MPa) during its course in the nozzle 1.
- the invention aims to overcome the disadvantages of that of the prior art by proposing, in a first aspect, a nozzle capable of maximizing the amount of movement produced by a two-phase liquid / vapor flow from the expansion of a saturating liquid.
- ejectors such as two-phase turbines can achieve higher energy performance especially for refrigeration systems or heat pumps with isenthalpe expansion valves.
- FIG. 5 illustrates a vapor compression refrigeration cycle, in the form of a T / S diagram, in which the mass entropy S
- Such isenthalpe expansion is far from achieving the performance of the ideal isentropic expansion, illustrated in FIG. 5 by the transition between the high condensation pressure (point 103) and the theoretical point (point 1O4 IS ).
- point 103 the high condensation pressure
- point 1O4 IS the theoretical point
- the amount of steam generated is minimal and the difference in the evaporation entropy of the saturating liquid is much greater than in the case of the isenthalpe expansion.
- FIGS. 6A to 6C show an ejector 60 of the prior art.
- This ejector mainly comprises a nozzle i as described with reference to FIG. 1 and a hollow body 62.
- the role of the nozzle 1 is to relax a high-pressure flushing liquid flow PFISI up to a theoretical low pressure Pth_ F is3 by increasing its speed, in order to cause a flow rate of fluid F2 at pressure PF2S2 significantly lower than PFISI .
- This fluid flow rate F 2 is usually a steam flow rate from the evaporation of a fluid at evaporation pressure PF2S2 less than the pressure P F isi and the pressure P ⁇ h_Meiss of the mixture after ejection.
- the hollow body 62 has a convergent 63, a mixing chamber 64 of constant section S4 and a conical divergent 65 of maximum section S5.
- the flow Fl enters the nozzle 1 at the section S1 and expands into a two-phase primary flow until it leaves the section S3.
- VFISI the speed of the primary flow Fl at section S1
- - PFISI the pressure of the primary flow Fl at the section S1;
- Pp2 S 2 the pressure of the secondary flow F2 at section S2;
- V ⁇ h ⁇ F2S3 the theoretical speed of the secondary flow F2 at section S3.
- the primary flow Fl and secondary flow F2 begin to mix in the convergent 63 at constant pressure and then enter the mixing chamber 64 in which a biphasic mixture is formed at theoretical velocity V ⁇ h_Meis4 and theoretical pressure P ⁇ hj "s4-
- the divergent 65 forms a diffuser for decelerating the two-phase mixing of fluid flows Fl and F2 up to a speed V ⁇ h_Meiss and transforming the kinetic energy into potential energy pressure.
- the pressure of the mixture increases in the divergent 65 to a theoretical outlet pressure Pm .
- FIGS. 6B and 6C This state of affairs is represented in FIGS. 6B and 6C on which the pressures and speeds defined above are respectively represented, the theory being represented in solid line, and the performance of the prior art in bold dashed line.
- the invention also relates to an ejector which does not have the disadvantages of the current state of the art.
- the invention relates to a nozzle capable of relaxing a saturating flow.
- This nozzle comprises a convergent, a neck, a tube, and a mixing element located in the tube, downstream of the neck, the mixing element being able to split the saturating liquid phase to mix with the vapor phase.
- the nozzle according to the invention aims to mix the vapor and liquid phases of the saturating liquid downstream of the neck, whereas in the current state of the art, it is sought to treat these two phases separately
- the Applicant has found that in the nozzles of the prior art, the liquid and the vapor are separated at the outlet of the neck, at the level of enlargement. Downstream of the neck, she noted a slippage between the liquid phase and the vapor phase: the vapor phase seeking to occupy the entire volume allotted to it spreads around the periphery of the central liquid flow. Therefore, the liquid jet at the outlet of the convergent is not accelerated by the steam formed by the trigger, the latter being placed at the periphery of the liquid jet.
- the invention therefore proposes mixing the vapor and liquid phases, which, as will be demonstrated later, considerably increases the amount of movement produced by the two-phase liquid / vapor flow coming from the expansion of the saturating liquid.
- the tube is a divergent section increasing, for example conical.
- the opening of this cone may be chosen to maintain the constant mass flow rate during the acceleration of the two-phase flow rate.
- the moderate conical divergent 4 may be replaced by a cylindrical tube.
- the convergent nozzle according to the invention comprises a needle to vary the neck section.
- the aforementioned mixing element is a fixed helix.
- this helix can be mobile.
- the mixing element may comprise forms of revolution of increasing sections.
- the nozzle according to the invention can be used in many devices, and in particular in an ejector, in a Hero turbine, in a Pelton turbine, or in a Francis turbine. More specifically, the invention also relates to an ejector comprising a body cr ⁇ ux r this hollow body having a convergent, a mixing chamber and a divergent, this ejector comprising, in the convergent, an expansion nozzle as mentioned above, the nozzle being adapted to to relax a primary flow of saturating liquid, in order to cause a secondary flow introduced into the convergent around this nozzle.
- the invention thus makes it possible to satisfactorily mix the vapor and liquid phases of the primary flow, and to drive the secondary flow much more efficiently than in the ejectors of the state of the art. This gives a real output pressure very close to the theoretical output pressure.
- the invention also relates to a Hero turbine comprising one or more hollow arms movable in rotation about an axis, this axis supplying the hollow arm (s) with a saturating liquid, this turbine comprising an expansion nozzle as mentioned above in FIG. end of each of the hollow arms.
- the invention also relates to a Pelton turbine comprising at least two buckets integral with a wheel that is rotatable about an axis, this turbine comprising at least one expansion nozzle as mentioned above, capable of projecting a two-phase jet in direction of the buckets.
- the invention also relates to a Francis-type turbine comprising at least one expansion nozzle as mentioned above and capable of projecting a two-phase jet towards the inside of a rotor of said turbine.
- the ejector according to the invention comprises a second mixing element, partly in the mixing chamber and partly in the diverging portion. This characteristic favors the mixing of the two-phase flow of the primary flow at the outlet of the nozzle with the secondary flow.

- the mixing element 5 is constituted by a fixed helix shown in FIG.
- FIG. 9 represents, in solid bold line, the evolution of the speed V of the flow rate D as a function of the pressure during its course in the nozzle 10.

- the hollow arms 21 are rotatable about a hollow axis 22 adapted to supply these hollow arms with a saturating liquid. It will be recalled that in a Hero-type turbine, the work is recovered directly on the axis 22 thanks to the impetus of the jets that start tangentially from the arms 21.
