TURBINE COMPONENTS
A fluid turbine apparatus comprising a convergent section, a fluid turbine section adjacent to the exit of the convergent section, the fluid turbine section comprising at least one fluid turbine operating with a ducted tunnel and annular rotor, and a divergent section adjacent to the fluid turbine section. The fluid enters through the convergent section and exits through the divergent section and the convergent and divergent sections are equipped with adapters to eliminate the dead zones created by the annular rotor and to provide a more uniform flow distribution over the cross section of the convergent and divergent sectors. Nozzles mounted on manifolds are used to inject compressed fluid along the interior walls of the convergent and/or divergent sections and a control system is employed to prevent boundary layer separation along the walls of the diffuser and maintain optimum flow conditions along the walls of the convergent.
