二维刚性摆动水翼的水动力分析

In order to study the performance of biomimetic propulsor, the unsteady hydrodynamic performance of 2D rigid oscillating hydrofoil is calculated numerically by the premise condition of BCF propulsion mode. The 2D oscillating mechanism of the connecting rod between rod and hydrofoil is simulated by commercial CFD software FLUENT. The mechanism is that the rod drives the hydrofoil. The results fit the numerical results by Yang Liang with the dynamic mesh method of Smoothing and Remeshing and the Real k-ε Non-eq turbulence model. And the performance of the flow fields behind hydrofoil and the unsteady hydrodynamic performance of 2D rigid oscillating hydrofoil is analysed in detail.
