Abstract
A continuous method and closed cycle system for converting thermal energy to mechanical energy comprises vaporizing means for converting a liquid working fluid stream to a predominately, by volume, vapor or an all vapor stream; turbine means operated by the stream for converting a portion of the vapor stream energy to mechanical shaft work; means for increasing the thermal and potential energy of the turbine exhaust stream and for condensing it to a substantially liquid stream; and means for recycling the liquid stream to the vaporizing means. The means for converting a working fluid liquid stream comprises a tube having a plurality of flow converging areas alternating with a plurality of flow diverging areas, each flow converging area confining said flow to a greater extent than the flow converging areas upstream thereof, and each flow diverging area expanding said flow to a greater extent than the flow diverging areas downstream thereof.
