Abstract:

A linearized theory is developed for unsteady two-dimensional cavity flow about thin hydrofoils at zero cavitation number. Expressions are presented for the lift and moment coefficients of a thin supercavitating foil performing arbitrary oscillations, in terms of the coefficient of a power series describing the chordwise amplitude distribution. They are applied to the case of a rigid foil performing heaving and pitching oscillations and to that of oscillating flaps. For very large depth-chord ratios, the lift and moment coefficients for pure heaving and pitching oscillations are identical to those obtained by previous workers. Author
