Geometric Design of the Limaçon-to-Circular Fluid Processing Machine

Abstract A limaçon machine is a rotary positive displacement device, in which the housing and rotor are constructed of Pascal curves. Previous works have been published to investigate working these machines two applications: gas expanders compressors. This article presents theoretical investigation into potential modifying profile simplify machine’s manufacturing process reduce production cost. The proposed modification will produce new characteristics for housing–rotor interaction. An outcome that motivates need obtain mathematical models interference describe volumetric relationship machine. also employs an optimization approach design best given set operating conditions, i.e., expander, compressor, pump. this study confirms validity its with favorable characteristics.
