One-dimensional (1D) aerodynamic performance predictions are very often conducted by researchers and designers during the preliminary design of centrifugal compressors. This paper focuses on a 1D prediction method for compressors with splitter blades, which is rarely seen in open literature. overall made different technical specifications. However, accuracy relies 1D-loss-models used. Therefore...

Thermoplastic use as labyrinth seals in rotating equipment is continuing to gain acceptance in the process industries. Presented in this paper is a discussion on thermoplastic use as a labyrinth seal material in centrifugal process compressors. Labyrinths made from engineering thermoplastics are used to improve efficiency, reliability, and installation time. An introduction to the polymer mater...

Stringent stability screening criteria by the American Petroleum Institute (API) result in higher level rotor stability analyses to be performed on more intermediate-pressure compressor rotors and in more detail. These high-level stability analyses include predictions of impeller and seal rotordynamic forces and even extra effort on design and analysis of special damping devices as a backup, su...
