Welcome to our in-depth exploration of secondary flows —perpendicular fluid motions caused by pressure gradients and centrifugal forces— and their impact on turbine performance.
This technical brief dives into the physics of secondary flows in a 1.5-stage Aachen turbine and demonstrates how Cadence’s Fidelity CFD platform can simulate and mitigate these inefficiencies.
Highlights:
- Vortex Formation: Explore how passage vortices (PV), horseshoe vortices (HSV), and tip-leakage vortices (TLV) disrupt flow and increase aerodynamic losses.
- Advanced Simulation: Learn how Fidelity Turbo and Fidelity Automesh create high-quality meshes and use turbulence models to analyze real-world flow patterns.
- Optimization Insights: Discover how simulation-driven design changes improve aerodynamics and reduce energy dissipation.
Uncover actionable strategies to minimize losses and maximize turbine efficiency.
