Abstract:
1. An optimized adiabatic expansion nozzle which comprises an inlet tube for receiving a liquid, a primary expansion tube surrounding said inlet tube in which said liquid expands in said primary expansion tube at a primary expansion ratio, a primary end cap at an end of said primary expansion tube opposite to said inlet tube, said primary end cap reversing flow direction of said expanded liquid into an adjacent one or more secondary expansion tubes, said liquid expands in said one or more secondary expansion tubes at a second expansion ratio, and secondary end caps positioned at an outlet end of each of said one or more secondary expansion tubes for reversing flow direction of said expanded liquid to flow over the outside of an adjacent one of said one or more said secondary end tubes, wherein said primary end cap and said secondary end cap have a curved shape with a rounding between a diameter 2r and a radius r of an outer one of said one or more secondary expansion tubes.
