• The finite element method for the unsteady two-dimensional inviscid rotational flow through a cascade proposed in the previous paper (l) was extended in order to apply to the varying flow rate case. The most important improved point is the treatments of the trailing vortex wake. Two basic oscillatory flows through flat plate cascades which have either parallel or normal velocity disturbance to the cascade were analysed. The calculated results agreed substantially with the existing one. Then the lift forces of a double-circular arc cascade were compared with that of the corresponding flat plate cascade. The present method is applicable to the flows through arbitrarily formed cascades with relatively large periodic and non-periodic variations of flow rate.
