    • Development of High-Pressure Ratio and Wide-Operating Range 700bar Compressor 
      Tokuyama, Shinichiro; Ujihara, Diogo Yoshikazu; Nakaniwa, Akihiro; Saburi, Satoshi (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Lecture 1: Pre-Salt development projects continue to expand offshore Brazil into ever deeper waters year after year. Consequently, the required Discharge Pressures for Re-Injection Compressors aboard FPSO’s are likely to ...
    • Development of High-Pressure Ratio and Wide-Operation Range 700bar Compressor 
      Tokuyama, Shinichiro; Ujihara, Diogo Yoshikazu; Nakaniwa, Akihiro; Saburi, Satoshi (Texas A&M University. Turbomachinery Laboratories, 2014)
      Pre-Salt development projects continue to expand offshore Brazil into ever deeper waters year after year. Consequently, the required Discharge Pressures for Re-Injection Compressors aboard FPSO’s are likely to exceed current ...
    • High Frequency Acoustic Excitation in Centrifugal Compressor and Adjacent Piping Vibration 
      Hirata, Daisuke; Nekomoto, Yoshitsugu; Ibrahim, Fady; Nakaniwa, Akihiro; van Beek, Pieter; Frediani, Luca (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      In a centrifugal compressor, interactions between impeller blades and stationary parts such as diffuser vanes will generate high frequency pressure pulsations. The frequencies of these pulsations, so called “blade passing ...

      Hirata, Daisuke; Nakaniwa, Akihiro; Nekomoto, Yoshitsugu; van Beek, Pieter; Ibrahim, Fady; Frediani, Luca (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
      In a centrifugal compressor, interactions between impeller blades and stationary parts such as diffuser vanes will generate high frequency pressure pulsations. The frequencies of these pulsations, so called “blade passing ...
    • Impeller Stall Induced by Reverse Propagation of Non-Uniform Flow 
      Iwamoto, Shinji; Shoji, Yoshiaki; Yoneda, Keizo; Nakaniwa, Akihiro; Barrington, Bryan (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      In the case of centrifugal compressors, minor non-uniform flow upstream of the impeller is induced by an asymmetrical configuration in the circumferential direction at the compressor suction casing. This non-uniform flow ...
    • Impeller Stall Induced By Reverse Propagation Of Non-Uniform Flow Generated At Return Channel 
      Iwamoto, Shinji; Yoneda, Keizo; Tokuyama, Shinichiro; Higuchi, Hirofumi; Nakaniwa, Akihiro; Barrington, Bryan (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      In the case of centrifugal compressors, minor non-uniform flow upstream of the impeller is induced by an asymmetrical configuration in the circumferential direction at the compressor suction casing. This non-uniform flow ...
    • Investigation Results for Surge Phenomena of Centrifugal Compressor Related with Piping Arrangements and Test Conditions 
      Kiuchi, Daisuke; Nakaniwa, Akihiro; Tokuyama, Shinichiro; Matsuyama, Keisuke (Texas A&M University. Turbomachinery Laboratories, 2013)
      The shop performance test of a hydrogen recycle gas compressor for refinery plant was conducted with the suction pressure of 50barA based on ASME PTC-10 Type-2 test. During testing, a surge phenomenon was observed at a ...
    • New Concept of On-Line Wash for Centrifugal Compressor 
      Tokuyama, Shinchiro; Mohit, Goenka; Nakaniwa, Akihiro; Mathew, Ajay; Subramani, Elumalai (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This paper introduces the development of new concept of on-line wash oil injection system which includes the optimization of quantity of washing oil, location of injection nozzles, direction of nozzle entry, hole size as ...
