The lecture provides an overview of challenging compressor applications (in terms of common aerodynamic criteria) focusing on two examples, due to their use of advanced analytical tools and test models. Development of DATUM ICS with Rotating Centrifugal Separator (RCS) technology combined rotary gas-liquid separation and centrifugal compressor flow path. Such a combination represents a new class of turbomachinery and leads to increased system compactness by significantly reducing the size and weight of installed equipment and eliminating large separation vessels often used on traditional compressor trains. An overview is given for the Dresser-Rand RCS development, multiphase mean-line and CFD modeling, and Demo tests, including the latest one at high pressure conditions, more challenging for separation. The test allowed better understanding of the aero- and thermodynamic behavior of the RCS and validated both compression and separation performance at demanding operating conditions. Centrifugal compressors in the refrigeration cycles of LNG production process are characterized by large flow coefficient and high machine Mach number. Therefore both compressed medium and high speed operation directly impact performance. An overview is given on a typical CFD analysis of high-Mach number application stage, along with its test validation on D-R development test rig. Discussion on optimization highlights both the mean-line level of design and analysis, when specialized tools are used for preliminary design, and the CFD level, through parametric studies.
