Abstract
A rotating liquid ring rotating casing gas turbine (10) has at least one liquid ring rotating casing (13) having an eccentrically mounted impeller (11) adapted to rotate within a surrounding liquid ring (14) so as to form chambers (15) of successively increasing volume between adjacent vanes of the impeller. A working fluid formed by high pressure gas is injected into the impeller where the chambers are narrow via a fluid inlet (19) within a static axial bore (23) of the impeller so as to rotate the impeller and in so doing the gas expands isentropically. A fluid outlet (20) within the static axial bore of the impeller and fluidly separated from the fluid inlet allows the working fluid to escape at low pressure and low temperature.

A rotating liquid ring rotating casing gas turbine, comprising:
- at least one liquid ring rotating casing having an eccentrically mounted impeller adapted to rotate within a surrounding liquid ring so as to form chambers of successively increasing volume between adjacent vanes of the impeller,
- a fluid inlet within a static axial bore of the impeller for injecting a fluid as a gas at high pressure into the impeller where the chambers are narrow so as to rotate the impeller and in so doing to expand essentially isentropically, and
- a fluid outlet within the static axial bore of the impeller and fluidly separated from the fluid inlet for allowing the fluid to escape at low pressure and low temperature.
