as a result of condensation of the working fluid the liquid in the liquid ring becomes heated and an equilibrium state is created that impedes further condensation for this reason it is believed that water may also be used as the liquid ring while in the embodiment described above a heated oil ring is proposed in order to avoid condensation of the steam this may give rise to undesirable mixing forming an oil water emulsion which may be undesirable furthermore reverting to fig2 steam enters the fluid inlet 19 at the upward left side of the turbine and heats the water ring in contact therewith the heated liquid ring cools during the few milliseconds that it takes to rotate through 2 3 radians approx 180 u00b0 when it approaches the lower end section of the turbine consequently some of the steam is absorbed by the liquid ring and does not generate shaft work for these reasons it is more effective to use a desiccant liquid ring such as brine which avoids both of these drawbacks as before steam enters the fluid inlet 19 and upon encountering the liquid desiccant ring in the expanding zone the steam condenses on the liquid interface the diffusion of water inside the liquid brine is extremely small approximately 10 u2212 9 m 2 s and the water depth at the brine steam interface will be only several microns within a short time interval of only.
