摘要
The paper discusses a mathematic model of the Weis-Fogh hydrofoil under the flow upstream with a separation vortex. The analysis makes use of a single-vortex model. We establish the motion equation of the vortex and the initial condition. Applying the complex function theory, we also obtain the analytic formula of the hydrodynamic integrations'which have the complex parameter and the singularity POint. The numeric results compare well with experiment.
