Mixer-ejector Technology Means Greater Efficiency

Conventional turbines operate by posing resistance to wind.  Well-established physical laws dictate that nearly half the available energy approaching an open-bladed turbine is diverted around the rotor face.  This lost energy generates turbulence instead of usable electricity.

Ogin Turbines are fundamentally different.  The mixer-ejector shroud system functions as a static pump that changes the pattern of airflow through and around the turbine.

  • The mixer shroud, surrounding the rotor plane, creates vortices of slower and faster airflow that mix out turbulence and reduce turbine backpressure.  Wind accelerates through the rotor, increasing power extraction.  Lower turbulence around the turbine lessens mechanical strain and reduces long-term O&M costs.
  • Exit air passes from the mixer into the larger ejector shroud.  At this stage, additional outside air is introduced, equalizing pressure with exterior wind passing by the turbine.  The ejector spreads the wake over a larger area, reducing turbulence aft of the turbine.  This rapid wake mitigation allows turbines to be positioned closer together.

The Ogin Turbine’s design dramatically increases the efficiency of both individual turbines as well as close arrays of multiple turbines – reducing the total footprint for a project of a given power output. Lower, more compact arrays to meet local energy needs can fit into local landscapes with reduced impacts compared to traditional approaches.
