ABSTRACT:
A water driven turbine has a divergent cone coupled to the exit end of the housing in which diameter of the cone increases with increasing distance from the exit end of the housing. A diverter formed of rigid material surrounds the free end of the cone and defines an annular space therebetween through which a flow of water passes to accelerate the flow exiting the turbine housing. The diverter is shorter in the length than the divergent cone and longitudinally overlaps the divergent cone. The diverter also has straight walls which are sloped to extend in the longitudinal direction away from the exit end of the housing at an inward incline between the leading end and the trailing end thereof.
