| 中文摘要: |
| 将数值优化软件modeFRONTIER同计算流体力学(CFD)软件相结合,对NACA0012翼型的气动性能进行优化。计算采用N-S方程作为主控方程以计算翼型气动性能,分别采用多目标遗传算法(MOGA)和多目标模拟退火算法(MOSA)作为翼型的气动性能优化算法。计算结果表明,优化后的翼型相对于优化前的翼型的气动性能有很大提高(升阻比增幅可达182%)。 |
| 英文摘要: |
| The combination of the optimization software,modeFRONTIER and the commercial CFD software is used to optimize the aerodynamic functions of the airfoil,NACA0012.The N-S equations are adopted for calculating the airfoil aerodynamic properties(Cl,Cd and etc).Two kinds of optimization algorithm,the Multi-Object Genetic Algorithm(MOGA) and the Multi-Object Simulated Annealing(MOSA),are used in the optimization process respectively.The optimized airfoils show remarkable improvement of its aerodynamic functions(The ratio of lift to drag increases up to 282%) relative to its original one. |
