运动参数对近波面拍动翼推进性能的影响
Effect of kinematic parameters on propulsion performance of flapping foil
摘要
Abstract
The effect of kinematic parameters on the propulsion performance of 2D rigid flapping foil nearby the wave surface was studied. At first, the numerical model of foil under the waves was built based on the computational fluid dynamic (CFD) technique. Then, using wave-generated by velocity inlet boundary method and dynamic mesh technology, both the motions and hydrodynamic performances of foil were simulated and analyzed. The performances of foils which were in infinite fluid and nearby the calm water surface were calculated and compared. The results show that the thrust, propulsive efficiency and the wave devouring efficiency of foil can be maximum when the phase difference between pitch and heave is appropriate. The wake can increase the gradient of foil’s wake vortex and decrease its range when the foil was near the wave surface or with the favorable phase difference between pitch and heave. As a result, the thrust and propulsive efficiency can be improved. In addition, it is beneficial to increase the thrust at larger pitch angle or heave amplitude and higher efficiency can get at larger pitch angle or smaller heave amplitude.关键词
