High efficiency transonic mixed-flow compressor method and apparatus

摘要

A method and apparatus for compression of elastic fluids such as air in a rotary continuous mixed flow transonic process particularly of interest in the turbomachinery field. The compressor comprises a housing (12) defining an annular wall (50) in which a rotor (22) is journaled, thereby defining an annular flowpath (24). The annular wall (50) has a cylindrical inlet (52a), a part-conical outlet (52b) and a smooth transitional intermediate portion (52c). The rotor (22) has blades (42) which closely conform to the inner surface of the annular wall (50).
