Abstract
High fidelity simulations are performed to study deep dynamic stall of a SD7003 airfoil in plunging motion. The numerical computations employ sixth-order compact schemes for spatial derivatives, interpolation and filtering on a staggered grid. The SD7003 profile undergoes a plunge motion at Re=60000, Ma=0.1, static angle of attack of 8 degrees and reduced frequency of 0.5. This configuration was adopted due to availability of data from experiments and simulations. Good agreement with previous work is found, especially in the earlier stages of the dynamic stall vortex (DSV) formation. Finally, proper orthogonal decomposition analysis (POD) of the simulated flow is performed. Only a few modes are necessary to recover the main features of the aerodynamic loading, showing promising results for creating a reduced order model of this type of flow
