Simulation Approaches#
Flow360 supports multiple approaches for turbomachinery simulation:
Single Passage Analysis: * Utilize periodic boundaries to model a single blade passage * Computational efficiency for parametric studies * Appropriate for steady-state design point analysis
Full Annulus Simulation: * Complete 360-degree model capturing blade count effects * Required for unequal blade counts and certain instabilities * Captures large-scale flow structures and asymmetries
Multiple Frame of Reference: * Models relative motion between rotating and stationary components * Steady-state approximation of rotor-stator interaction * Efficient for multi-stage preliminary design
Unsteady Simulation: * Time-accurate capture of blade passing effects * Required for transient phenomena and acoustic analysis * Predicts blade row interaction and flow instabilities
