Unsteady flowfields around airfoils oscillating in pitch and associated dynamic stall phenomena are inves-tigated. A viscous flow analysis and a simplified vortical flow analysis, both based on an integro-differentialformulation of the Navier-Stokes equations are developed and calibrated. The formulation of the viscous flowanalysis confines computations only to the viscous flow zone and leads to an efficient zonal solution procedure.In the simplified vortical flow analysis, computational demands are greatly reduced by partial analytic eval-uations. Simulated flowfields and computed aerodynamic loads are in good agreement with available experi-mental data.
