Uniformity of flow distribution after centrifugal compressor inlet has a substantial impact on compressor performance. Liquid present in the gas affects performance of downstream stage components. A CFD study of two-phase flow in the compressor inlet is discussed. An inlet design is derived from the family of Dresser-Rand DATUM® compressors and adapted to actual conditions. Analysis of two-phase flow field and losses is presented. Conclusions are made on the applicability of the proposed inlet configuration to selected application and on flexibility of the DATUM product line.
