CENTRIFUGAL STAGE PERFORMANCE PREDICTION AND VALIDATION FOR HIGH MACH NUMBER APPLICATIONS
Steve Kowalski is an Aero-Thermo Engineer in the Research and Development Department of DresserRand. His responsibilities include the design, development and analysis of aerodynamic components of centrifugal compressors. He has been employed at Dresser-Rand since 2007. He holds a B.S. degree from Michigan State University (Mechanical Engineering, 2002) and an M.S. degree from Michigan State University (Mechanical Engineering, 2005). Prior to joining Dresser-Rand, he worked as a teaching/research assistant at Michigan State University.
High Inlet Relative Mach Number Centrifugal Compressor Impeller Design
This document presents an overview of impeller inlet relative Mach number, how the parameter is calculated, and its importance as an indicator of impeller performance. Comments are also offered regarding the comparison of inlet relative Mach numbers obtained from different compressor vendors. A sample impeller is used to illustrate the various methods used to calculate the inlet relative Mach number. Test data for that impeller is also offered to indicate the performance map achievable with high Mach number designs. Please note that this document is not intended to be an all-inclusive treatment of the subject; rather, it summarizes the OEM’s methodologies and perspective.Copyright © 2007 by ASME
