CFD Simulation of Centrifugal Compressor

This session focuses on the complete workflow for performing CFD simulations of centrifugal compressors using Ansys CFX. You will learn how to set up, run, and analyze steady-state and transient simulations to evaluate the performance, efficiency, and flow characteristics of centrifugal compressors.

Topics include:

• Geometry preparation and meshing (BladeGen / TurboGrid / Ansys Meshing)
• Boundary condition setup for compressor inlet and outlet
• Modeling of rotating domains and interfaces
• Selection of turbulence models
• Monitoring parameters like pressure ratio, efficiency, and power consumption
• Post-processing results such as velocity vectors, pressure contours, and performance curves

By the end, you’ll understand how to accurately simulate flow behavior inside a centrifugal compressor, identify losses, and optimize blade design and diffuser geometry for improved performance.
