摘要： A screw compressor or expander is provided, comprising: a male rotor (210) having a first axial length extending from an inlet portion to an outlet portion and a set of lobes (212) with a variable profile extending along the first axial length; and a female rotor (214) having a second axial length extending from the inlet portion to the outlet portion and a set of grooves (216) with a variable profile extending along the second axial length, the set of grooves mating with the set of lobes. At least a portion of the male rotor (210) and the female rotor (212) each have a non-cylindrical configuration with a non-constant outer diameter, and the male rotor and the female rotor have an ogive configuration where the outer diameter of each respective rotor decreases in an arc along at least a portion of the respective axial length from the inlet portion to the outlet portion.
