the road ahead: challenges and opportunities in bladed disk modeling

Multiphysics Coupling: Bladed disks experience a complex interplay of aerodynamic, thermal, and structural forces. Modeling these interactions effectively remains a challenge. Current methods often involve uncoupled simulations, neglecting the influence of one physics domain on another. Material Characterization: Material properties like creep, fatigue, and damping are crucial for long-term performance prediction. Current characterization methods often lack the resolution to capture the intricate behavior of advanced materials used in high-performance engines. Manufacturing Imperfections: Real-world disks exhibit manufacturing variations and surface roughness, impacting vibration and stress distribution. Existing models often struggle to incorporate these effects accurately. High-Fidelity Modeling: High-fidelity models incorporating all the complexities mentioned above become computationally expensive and time-consuming. Striking a balance between accuracy and practicality remains a challenge.
