Flow-Induced Vibration of Transonic Turbine Cascades Considering Viscosity and Shock Wave Effects
- 발행 : 2006.05.01
초록
In this study, a fluid/structure coupled analysis system for simulating complex flow-induced vibration (FIV) phenomenon of cascades has been developed. The flow is modeled using Euler and Wavier-Stokes equations with different turbulent models. The fluid domains are modeled using the unstructured grid system with dynamic deformations due to the motion of structural boundary. The Spalart-Allmaras (S-A) and the SST
