Rotary Equipment & Turbomachinery: Multistage Compressor, 2 Rotor & Stator Rows

Description

This module covers multistage compressor simulation using CFD, applying rotary equipment and turbomachinery modeling principles to a compressor configuration with two rotor and two stator rows. Multistage compressors are widely used across mechanical engineering applications, including gas turbines, HVAC systems, and process industries, making this a foundational skill for turbomachinery-focused CFD work.

Methodology

The simulation setup covers configuring rotating reference frames for the rotor stages, defining interface conditions between rotor and stator domains, and applying turbulence models suited to compressor flow. Boundary conditions specific to compressor operation are established, and the simulation is run with convergence monitored throughout the solution process.

Conclusion

The analysis examines flow patterns, pressure ratios, and temperature changes across the compressor stages, visualized through velocity fields, pressure distributions, and streamlines. This understanding supports the analysis and optimization of compression systems such as gas turbine engines, industrial air compressors, and refrigeration systems, and builds core skills for tackling advanced turbomachinery problems in mechanical engineering.
