Calculated Hydrodynamic Loads on an Oscillating Hydrofoil

摘要

Formulas for the amplitude and phase angle of the twodimensional unsteady lift and moment on an oscillating foil are derived together with formulas for the reduced lift and moment coefficients. Numerical values of the reduced force coefficients and associated phase angles are presented in graphs and tables. A sample calculation is included to demonstrate the use of the formulas and graphs.
