| 摘要： | In order to improve the anti-cavitating performance of the hydrofoil, some appropriate transformation was taken place on the suction side of the two-dimensional foil.Via integrating the technology of the geometric parameterization, the panel method and the optimization algorithm, the hydrofoil was reconstructed with anti-cavitating consideration.The modification was achieved by setting up a vaulting barrier on the suction side of the section and using cubic B-spline to parameterized express the shape.The basis data for the genetic algorithm objective function, which founded for the NACA0010 airfoil optimization ,was accessed by the panel method program in forecasting the foil performance under a certain condition.The instantaneous simulation of the prototype and the modified foil flow with cavitating was carried out by using Fluent.The differences between the contours of gas volume fraction, which reflects the degree of foil in cavitating, were acquired.And it confirmed the intended purpose of the modification.This hydrofoil design method could be a reference for the three-dimensional hydrofoil design. |
