Two-Dimensional Dynamics CFD Simulation of Voith-Schneider Cycloidal Propeller

The paper analyzed the motion state of VSP cycloidal propeller with unsteady oscillation and obtained the analytical expression of the maximum angular acceleration for rotation of the blade with the angular velocity of revolution and eccentricity. Two sets of cycloidal propellers with opposite revolution were constructed based on this and CFD simulation was applied to simulate the working conditions in a two-dimensional plane where the mechanism generates different directions and magnitudes of thrust for autonomous propulsion from the stationary state, and the dynamic performance of the propellers was obtained from the motion state of the mechanism. The simulation results showed that the variation pattern of the thrust coefficient of the cycloidal propeller with respect to the angle of revolution of the blades depends only on the magnitude of the mechanism eccentricity.
