Abstract:
A method of driving a turbine in rotation, said turbine being connected to an upstream fluid feed channel and to a downstream ejection channel, said method comprising the steps of:admitting a primary fluid into said upstream fluid feed channel, said upstream channel converging from upstream to downstream for generating a flow of said primary fluid at a mass flow rate Dp, and said primary fluid having, in a downstream portion of said upstream channel, a pressure Pp which is lower than the pressure Pa of an external ambient medium, a speed Vp, and a flow which is substantially without disturbances;driving said turbine in rotation by passing said primary fluid over the blades of said turbine;injecting a secondary fluid into said downstream channel, said secondary fluid having a pressure Ps greater than said pressure Pa, a speed Vs greater than said speed Vp, and a flow rate Ds less than said mass flow rate Dp of said primary fluid;mixing said primary and secondary fluids in said downstream channel to obtain a homogeneous mixture in said downstream channel having a mass flow rate substantially equal to the sum of said mass flow rates Dp and Ds of said primary and secondary fluids; andejecting said mixture at the outlet of said downstream channel into said ambient medium via an outlet section of said downstream channel.
