Analysis of Transonic Limit Cycle Oscillations under Uncertainty

摘要

1. Density is proportional to the aerodynamic forces, thus effecting the LCO behaviour almost linearly 2. LCO behaviour is very sensitive to Mach number due to the movement of the shock wave 3. PCE can capture bifurcation boundaries well when adaptive sampling is used 4. The bifurcation boundaries take different forms for each structural parameter.
