Abstract:
This report gives a review of the various types of unsteady flow phenomena that occur within a turbomachine and examines existing methods for computing several of these flows. Then, we discuss a method for applying two- dimensional, unsteady, thin airfoil theory in a stripwise manner to computer the unsteady forces and moments on the shaft of a rotor operating within a nonuniform inflow. Techniques for computing these unsteady forces and moments on a rotor blade row with rake and skew are included.
