ABSTRACT:
A method and apparatus for providing an improved regenerative turbine driven by a liquid or gaseous fluid. The turbine has a housing with a primary inlet and an auxiliary inlet. The driving fluid in the primary inlet is maintained at near stagnation pressure conditions. As the primary driving fluid passes through the regenerative turbine motor channel, it describes a helical path, imparting energy from the fluid to the rotor. The auxiliary fluid inlet feeds fluid to the exhaust part of the rotor channel tangential to the helical path of the primary fluid and increases the rotational motion of the exhaust fluid. The pressure ratio between the fluid inlet and the fluid exhaust is thereby increased and results in improved turbine efficiency. Secondary sources of energy for driving the turbine provide alternative driving fluids.
